Product Summary

The AD7845BRZ is a 4-quadrant multiplying D/A converter with an on-chip amplifier. It is fabricated on the LC2MOS process, which allows precision linear components and digital circuitry to be implemented on the same chip. The 12 data inputs drive latches which are controlled by standard CS and WR signals, making microprocessor interfacing simple. The applications of the AD7845BRZ include Automatic Test Equipment, Digital Attenuators, Programmable Power Supplies, Programmable Gain Amplifiers and Digital-to-4–20 mA Converters.
