MAX500BEWE+ [Analog Devices]

The MAX500 is a quad-channel, 8-bit voltage-output digital-to-analog converter (DAC) featuring a cascadable serial interface. It includes four output buffer amplifiers and input logic for easy use with two- or three-wire serial interfaces. In systems with multiple MAX500s, only one serial data line is required to load all DACs by cascading them. The device contains double-buffered logic and a 10-bit shift register, allowing all four DACs to be updated simultaneously using one control signal. There are three reference inputs, enabling independent range setting for two DACs while the other two track each other. The MAX500 achieves 8-bit performance over the full operating temperature range without external trimming. Output buffers provide high slew rate and fast settling time, suitable for single or dual supply operation.
