OBPRODUCT DESCRIPTION
SThe AD392 is a quad I2-bit, high-speed, voltage output digital-to-
Oanalog converter with readback in a 32-pin hermetically sealed
package. The design is based on a custom IC interface to complete
LI2-bit DAC chips which reduces chip count and provides high
reliability. The AD392 is ideal for systems requiring digital
Econtrol of many analog voltages and for the monitoring of these
Tanalog voltages especially where board space is a premium. Such
Eapplications include ATE, robotics, process controllers and
PRODUCT HIGHLIGHTS
1. The AD392 is packaged in a 32-pin DIP and is a complete
solution to space constraint multiple DAC applications.
2. Readback capability provides system monitor of DAC output
useful in ATE, robotics or any closed-loop system.
3. Fast bus access time of 40ns maximum allows for fast system
updating compatible with high-speed microprocessing.
4. Simultaneous reset to zero volts output is extremely useful

signals permit the registers of the four DACs to be loaded
sequentially and the outputs to be simultaneously updated.
The AD392 outputs are calibrated for a :!:lOV output range
with positive true offset binary input coding.
The AD392 is packaged in a 32-lead ceramic package and is
hermetically sealed. The AD392 is specified for operation over
the 0 to + 70°C temperature range.
