The HA17008R series are 8-bit monolithic D/A converters which have built in, a reference current amplifier, an R-2R ladder resistor, and 8 high speed current switches.
By setting the reference voltage and resistance, the maximum output current can be freely varied in response to the application.
The reference current is distributed to the current value for each bit by the R-2R ladder resistor, and the maximum output current is 255/256 of the reference current. For example, if the input reference current is 2.0 mA, then the maximum available output current is 1.992 mA.
Applications for the HA17008R are wide ranging, and include CRT displays, stepping motor control, programmable power supplies, audio equipment, and attenuators.

*Linearity of ±0.19% (±1/2 LSB) guaranteed.

The MP7541B is a pin-compatible replacement which offers superior performance in latch-up and ESD protection versus the comparable 7541 and 7541A. The high ESD protection will reduce failures caused by mishandling. These devices are manufactured using patented advanced thin film resistors on a double metal CMOS process which result in ultra stable thin film and superior long life reliability and stability. The MP7541B incorporates a bit decoding technique yielding lower glitch, higherspeed and excellent accuracy over temperature and time. The MP7541B’s outstanding features are:
Stability: Both Integral Non-Linearity (INL) and Differential-Non-Linearity (DNL) are rated at 0.2 ppm/°C maximum. Monotonicity is guaranteed over the entire temperature range. Gain Temperature Coefficient (TCGE) is 2.0 ppm/°C typical.

The MC74VHCT4051 utilizes silicon–gate CMOS technology to achieve fast propagation delays, low ON resistances, and low OFF leakage currents. This analog multiplexer/demultiplexer controls analog voltages that may vary across the complete power supply range (from VCC to GND).
The VHCT4051 is identical in pinout to the high–speed HC4051A and the metal–gate MC14051B. The Channel–Select inputs determine which one of the Analog Inputs/Outputs is to be connected by means of an analog switch to the Common Output/Input. When the Enable pin is HIGH, all analog switches are turned off.
The Channel–Select and Enable inputs are compatible with TTL–type input thresholds. The input protection circuitry on this device allows overvoltage tolerance on the input, allowing the device to be used as a logic–level translator from 3.0V CMOS logic to 5.0V CMOS Logic or from 1.8V CMOS logic to 3.0V CMOS Logic while operating at the higher–voltage power supply.
The MC74VHCT4051 input structure provides protection when voltages up to 7V are applied, regardless of the supply voltage. This allows the MC74VHCT4051 to be used to interface 5V circuits to 3V circuits.
This device has been designed so that the ON resistance (Ron) is more linear over input voltage than Ron of metal–gate CMOS analog switches.
For a multiplexer/demultiplexer with channel–select latches, see VHC4351.

*Fast Switching and Propagation Speeds
*Low Crosstalk Between Switches
*Diode Protection on All Inputs/Outputs
*Analog Power Supply Range (VCC – GND) = 2.0 to 6.0 V
*Digital (Control) Power Supply Range (VCC – GND) = 2.0 to 6.0 V
*Improved Linearity and Lower ON Resistance Than Metal–Gate Counterparts
*Low Noise
*In Compliance With the Requirements of JEDEC Standard No. 7A

The MC54/74HC4066A utilizes silicon–gate CMOS technology to achieve fast propagation delays, low ON resistances, and low OFF–channel leakage current. This bilateral switch/multiplexer/demultiplexer controls analog and digital voltages that may vary across the full power–supply range (from VCC to GND).

The ON/OFF control inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.

The HA-2556 is a monolithic, high speed, four quadrant, analog multiplier constructed in the Intersil Dielectrically Isolated High Frequency Process.
The voltage output simplifies many designs by eliminating the current-to-voltage conversion stage required for current output multipliers.
The HA-2556 provides a 450V/μs slew rate and maintains 52MHz and 57MHz bandwidths for the X and Y channels respectively, making it an ideal part for use in video systems.
The suitability for precision video applications is demonstrated further by the Y-Channel 0.1dB gain flatness to 5.0MHz, 1.5% multiplication error, -50dB feedthrough and differential inputs with 8μA bias current. The HA-2556 also has low differential gain (0.1%) and phase (0.1°) errors.
The HA-2556 is well suited for AGC circuits as well as mixer applications for sonar, radar, and medical imaging equipment.
The HA-2556 is not limited to multiplication applications only; frequency doubling, power detection, as well as many other configurations are possible.

The Comstron Model PSC-4490 is a Nyquist bandpass filter used in a DAC( digital to analog converter). The purpose of the filter is to normalize the amplitude response of an input o(Sin x)/xo signal spectrum, and to reject unwanted frequencies while maintaining low group delay variation in the passband. The equalizing shape over the passband is |x/sin x|2 where where x = (∮f)/fs and fs=50.0 MSPS (sampling rate).

Organization and Application
The ACT8502 consists of six 16 channel muxes arranged as shown in the Block Diagram.
The ACT8502 design is inherently Radiation Hard due to the HS1840RH Multiplexers as well as
Microsemi Corp.
Transient Suppressors (Reference Microsemi MicroNotes Series 050 - page 14).
48 channels addressable by Bus A0~A3, in Three 16 channel blocks, each block enabled
Each block connects the addressed channel to two outputs, "Output" and "Current".
This technique enables selecting and reading a remote resistive sensor without the MUX
resistance being part of the measurement.
For grounded sensors, this is done by passing current to the sensor by means of the "Current" pin and reading the resultant voltage (proportional to the sensor resistance) at the "Output" pin.
NOTE: It is recommended that all "NC or "no connect pin", be grounded.
This eliminates or minimizes any ESD or static buildup.
