CMOS, Quad, Serial Interface 8-Bit DAC

The MAX500 is a quad, 8-bit, voltage-output digital-to-analog converter (DAC) with a cascadable serial interface. The IC includes four output buffer amplifiers and input logic for an easy-to-use, two- or three-wire serial interface. In a system with several MAX500s, only one serial data line is required to load all the DACs by cascading them. The MAX500 contains double-buffered logic and a 10-bit shift register that allows all four DACs to be updated simultaneously using one control signal. There are three reference inputs so the range of two of the DACs can be independently set while the other two DACs track each other.

The MAX500 achieves 8-bit performance over the full operating temperature range without external trimming.
