DESCRIPTION
The DAC7800, DAC7801 and DAC7802 are members of a new family of monolithic dual 12-bit CMOS multiplying Digital-to-Analog Converters (DACs). The digital interface speed and the AC multiplying performance are achieved by using an advanced CMOS process optimized for data conversion circuits. High stability on-chip resistors provide true 12-bit integral and differential linearity over the wide industrial temperature range of –40°C to +85°C.
The DAC7800 features a serial interface capable of clockingin data at a rate of at least 10MHz.

DESCRIPTION
The INA321 family is a series of rail-to-rail output, micropower CMOS instrumentation amplifiers that offer wide-range, single-supply, as well as bipolar-supply operation. The INA321 family provides low-cost, low-noise amplification of differential signals with micropower current consumption of 40μA. When shutdown, the INA321 has a quiescent current of less than 1μA. Returning to normal operations within microseconds, the shutdown feature makes the INA321 optimal for low-power battery or multiplexing applications.
Configured internally for 5V/V gain, the INA321 offers exceptional flexibility with user-programmable external gain resistors. The INA321 reduces common-mode error over frequency and with CMRR remaining high up to 3kHz, line noise and line harmonics are rejected.
The low-power design does not compromise on bandwidth or slew rate, making the INA321 ideal for driving sample Analog-to-Digital (A/D) converters as well as general-purpose applications.

DESCRIPTION
The REG104 is a family of low-noise, low-dropout linear regulators with low ground pin current. Its new DMOS topology provides significant improvement over previous designs, including low dropout voltage (only 230mV typ at full load), and better transient performance. In addition, no output capacitor is required for stability, unlike conventional low dropout regulators that are difficult to compensate and require expensive low ESR capacitors greater than 1μF.
Typical ground pin current is only 1.7mA (at IOUT = 1A) and drops to 0.5μA in not enabled mode. Unlike regulators with PNP pass devices, quiescent current remains relatively constant over load variations and under dropout conditions.
The REG104 has very low output noise (typically 33μVRMS for VOUT = 3.3V with CNR = 0.01μF), making it ideal for use in portable communications equipment. On-chip trimming results in high output voltage accuracy. Accuracy is maintained over temperature, line, and load variations. Key parameters are tested over the specified temperature range (–40°C to +85°C).
The REG104 is well protected—internal circuitry provides a current limit which protects the load from damage. Thermal protection circuitry keeps the chip from being damaged by excessive temperature. The REG104 is available in the DDPAK-5 and the SOT223-5.

DESCRIPTION
The OPA2680 represents a major step forward in unity gain stable, voltage feedback op amps.
A new internal architecture provides slew rate and full power bandwidth previously found only in wideband current feedback op amps.
A new output stage architecture delivers high currents with a minimal headroom requirement.
These combine to give exceptional single supply operation.
Using a single +5V supply, the OPA2680 can deliver a 1V to 4V output swing with over 100mA drive current and 150MHz bandwidth.
This combination of features makes the OPA2680 an ideal RGB line driver or single supply ADC input driver.
The OPA2680’s low 6.4mA/ch. supply current is precisely trimmed at 25°C.
This trim, along with low temperature drift, guarantees lower maximum supply current
than competing products.
System power may be reduced further using the optional disable control pin (SO-14 package only).
Leaving this disable pin open, or holding it high, will operate the OPA2680N normally.
If pulled low, the OPA2680N supply current drops to less than 600mA while the output goes into a high impedance state.

FEATURES
*WIDEBAND +5V OPERATION: 220MHz (G = 2)
*HIGH OUTPUT CURRENT: 150mA
*OUTPUT VOLTAGE SWING: ±4.0V
*HIGH SLEW RATE: 1800V/ms
*LOW SUPPLY CURRENT: 6.4mA/Ch.
*LOW DISABLED CURRENT: 300mA/Ch.
*ENABLE/DISABLE TIME: 25ns/100ns

APPLICATIONS
*VIDEO LINE DRIVING
*xDS*LINE DRIVER/RECEIVER
*HIGH SPEED IMAGING CHANNELS
*ADC BUFFERS
*PORTABLE INSTRUMENTS
*TRANSIMPEDANCE AMPLIFIERS
