ADI AD7549KN

Current - Unbuffered并联15V-40°C ~ 85°C

Overview

The AD7549KN is a monolithic dual, 12-bit, current output D/A converter. It is packaged in both 0.3" wide 20-pin DIPs and in 20-terminal surface mount packages. Both DACs provide four quadrant multiplication capabilities with a separate reference input and feedback resistor for each DAC. The monolithic construction ensures excellent thermal tracking and gain error tracking between the two DACs.

The DACs in the AD7549KN are each loaded in three 4-bit nibbles. The control logic is designed for easy processor interfacing. Input and DAC register loading is accomplished using address lines A0, A1, A2, and CS, WR lines. A logic high level on the CLR input clears all registers. Both DACs may be simultaneously update using the UPD input.
