Product Summary

The ad7549jn is a power rectifier. The ad7549jn is a monolithic dual, I2-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 ad7549jn 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 AO, AI, A2 and CS, WR lines. A logic high level on the CLR input clears all registers. Both DACs may be simultaneously updated using the UPD input. The applications of the ad7549jn include Programmable Filters, Automatic Test Equipment, Microcomputer Based Process Control, Audio Systems, Programmable Power Supplies, Synchro Applications.
