... GENERAL OVERVIEW The MCP4801, MCP4811 and MCP4821 are single channel voltage-output 8-bit, 10-bit and 12-bit DAC devices, respectively. These devices include rail-to-rail output amplifier, internal voltage reference, shutdown and reset-management circuitry. The devices use an SPI serial communication interface and operate with a single supply voltage from 2 ...
