15-Bit Linearity and Monotonicity:

DAC input logic (allowing simultaneous update of all

–40°C to 85°C

DACs), and provides

Programmable Reset to Mid-Scale

asynchronous reset clears all registers to a mid-scale

or Zero-Scale

•

Double-Buffered Data Inputs

DAC7634 can operate from a single 5-V supply or

from 5-V and –5 V supplies.

Low power and small size per DAC make the
