The PA84 is a high voltage operational amplifier designed for output voltage swings up to ±145V with a dual supply or 290V with a single supply. Two versions are available. The new PA84S, fast settling amplifier can absorb differential input overvoltages up to ±50V while the established PA84 and PA84A can handle differential input overvoltages of up to ±300V. Both versions are protected against common mode transients and overvoltages up to the supply rails. High accuracy is achieved with a cascode input circuit configuration. All internal biasing is referenced to a zener diode fed by a FET constant current source. As a result, the PA84 features an unprecedented supply range and excellent supply rejection. The output stage is biased-on for linear operation. External phase compensation allows for user flexibility in obtaining the maximum slew rate. Fixed current limits protect these amplifiers against shorts to common at supply voltages up to 150V. For operation into inductive loads, two external flyback pulse protection diodes are recommended. However, a heatsink may be necessary to maintain the proper case temperature under normal operating conditions.
This hybrid integrated circuit utilizes a beryllia (BeO) substrate, thick film resistors, ceramic capacitors and semiconductor chips to maximize reliability, minimize size and give top performance. Ultrasonically bonded aluminum wires provide reliable interconnections at all operating temperatures. The 8-pin TO-3 package is hermetically sealed and electrically isolated. The use of compressible thermal isolation washers and/or improper mounting torque will void the product warranty. Please see “General Operating Considerations”.

The PA 16 and PA 16A are wideband, high output current operational amplifiers designed to drive resistive, inductive and capacitive loads. Their complementary “collector output” stage can swing close to the supply rails and is protected against inductive kickback. For optimum linearity, the output stage is biased for class A/B operation. The safe operating area (SOA) can be observed for all operating conditions by selection of user programmable, current limiting resistors (down to 10mA). Both amplifiers are internally compensated but are not recommended for use as unity gain followers. For continuous operation under load, mounting on a heatsink of proper rating is recommended.

The PA51 and PA51A are high voltage, high output current operational amplifiers designed to drive resistive, inductive and capacitive loads. Their complementary common emitter output stage is the simple class C type optimized for low frequency applications where crossover distortion is not critical.
These amplifiers are not recommended for audio, transducer or deflection coil drive circuits. The safe operating area (SOA) is fully specified and can be observed for all operating conditions by selection of user programmable current limiting resistors. Both amplifiers are internally compensated for all gain settings. For continuous operation under load, mounting on a heatsink of proper rating is recommended. Do not use isolation washers!

The linear relationship of torque output to current input of the modern torque motor makes this simple control circuit ideal for many material processing and testing applications. The sense resistor develops a feedback voltage proportional to motor current and the small signal properties of the Power Op Amp insure accuracy. With this closed loop operation, temperature induced impedance variations of the motor winding are automatically compensated.

 The AD202 and AD204 are general purpose, two-port, transformer- coupled isolation amplifiers that may be used in a broad range of applications where input signals must be measured,
processed, and/or transmitted without a galvanic connection.
 These industry standard isolation amplifiers offer a complete isolation function, with both signal and power isolation provided for in a single compact plastic SIP or DIP style package. The
primary distinction between the AD202 and the AD204 is that the AD202 is powered directly from a 15 V dc supply while the AD204 is powered by an externally supplied clock, such as the
recommended AD246 Clock Driver.
 The AD202 and AD204 provide total galvanic isolation between the input and output stages of the isolation amplifier through the use of internal transformer-coupling. The functionally complete AD202 and AD204 eliminate the need for an external, user-supplied dc-to-dc converter. This permits the designer to minimize the necessary circuit overhead and consequently reduce the overall design and component costs.
 The design of the AD202 and AD204 emphasizes maximum flexibility and ease of use, including the availability of an uncommitted op amp on the input stage. They feature a bipolar ±5 V output range, an adjustable gain range of from 1V/V to 100 V/V, ± 0.025% max nonlinearity (K grade), 130 dB of CMR, and the AD204 consumes a low 35 mW of power.
 The functional block diagrams can be seen in Figures 1a and 1b.

-The AD202 and AD204 are full-featured isolators offering numerous benefits to the user:
* Small Size: The AD202 and AD204 are available in SIP and DIP form packages. The SIP package is just 0.25" wide, giving the user a channel density of four channels per inch. The isolation barrier is positioned to maximize input to output spacing. For applications requiring a low profile, the DIP package provides a height of just 0.350".
* High Accuracy: With a maximum nonlinearity of ±0.025% for the AD202K/AD204K (±0.05% for the AD202J/AD204J) and low drift over temperature, the AD202 and AD204 provide high isolation without loss of signal integrity.
* Low Power: Power consumption of 35 mW (AD204) and 75 mW (AD202) over the full signal range makes these isolators ideal for use in applications with large channel counts or tight
power budgets.
* Wide Bandwidth: The AD204’s full-power bandwidth of 5 kHz makes it useful for wideband signals. It is also effective in applications like control loops, where limited bandwidth could result in instability.
* Excellent Common-Mode Performance: The AD202K/ AD204K provide ±2000 V pk continuous common-mode isolation, while the AD202J/AD204J provide ±1000 V pk continuous common-mode isolation. All models have a total common-mode input capacitance of less than 5 pF inclusive of power isolation.
This results in CMR ranging from 130 dB at a gain of 100 dB to 104 dB (minimum at unity gain) and very low leakage current 2 mA maximum).
* Flexible Input: An uncommitted op amp is provided at the input of all models. This provides buffering and gain as required, and facilitates many alternative input functions including filtering, summing, high voltage ranges, and current (transimpedance) input.
* Isolated Power: The AD204 can supply isolated power of ±7.5 V at 2 mA. This is sufficient to operate a low-drift input preamp, provide excitation to a semiconductor strain gage, or power any of a wide range of user-supplied ancillary circuits. The AD202 can supply ±7.5 V at 0.4 mA, which is sufficient to operate adjustment networks or low power references and op amps, or to provide an open-input alarm.
