The Analog Devices AD394 and AD395 are quad 12-bit, high-speed, low-power voltage output multiplying digital-to-analog converters (DACs) housed in a compact 28-pin hybrid package. The design utilizes proprietary latched 12-bit CMOS DAC chips to reduce component count and ensure high reliability.
These devices provide full four-quadrant multiplication per DAC and are ideal for applications requiring digital control of multiple analog voltages where board space is at a premium, such as automatic test equipment and process controllers. The AD394 offers a bipolar output range (+10V), while the AD395 provides a unipolar range (0V to +10V). Both models feature factory-trimmed gain and offset with full scale accuracy of ±0.05% at 25°C.
| Full Scale Accuracy (AD394/AD395) | +0.05% of FSR at 25°C |
|---|---|
| Settling Time (to ±1/2LSB) | 15 µs Max |
| Package Type | 28-lead metal package |
| Operating Temperature Range (Standard) | 0 to +70°C |
The AD394 outputs provide a +10V bipolar output range with positive-true offset binary input coding.
The AD395 outputs provide a 0V to +10V unipolar output range with straight binary input coding.
Yes, both models are available for operation over extended temperature ranges compliant with MIL-STD-883.
