Digital-to-4–20 mA Converters GENERAL DESCRIPTION PRODUCT HIGHLIGHTS The AD7845 is the industry’s first 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. 1. Voltage Output Multiplying DAC
The AD7845 is the first DAC which has a full 4-quadrant
multiplying capability and an output amplifier on chip. All
specifications include amplifier performance. The 12 data inputs drive latches which are controlled by standard CS and WR signals, making microprocessor interfacing …
