S9408S Datasheet PDF - Summit Microelectronics

OVERVIEW
The S9408 DACPOT™ is a serial input, voltage output, quad 8-bit digital to analog converter. The S9408 operates from a single +2.7V to +5.5V supply. Internal precision buffers swing rail-to-rail and the reference input range includes both ground and the positive supply.
The S9408 integrates four 8-bit DACs and their associated circuits which include an enhanced unity-gain operational amplifier output, an 8-bit data latch, an 8-bit non volatile register, and an industry-standard serial interface for reading and writing data to the DACs’ data latches and registers. The DACs are independently programmable and each has its own electrically isolated Vreference inputs.
