AD7549JN Datasheet PDF - ADI

●Product Details

●The AD7549 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 AD7549 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.
