MCP4921/4922 4.0 GENERAL OVERVIEW The MCP492X devices are voltage output string DACs. These devices include input amplifiers, rail-to-rail out- put amplifiers, reference buffers, shutdown and reset- management circuitry. Serial communication conforms to the SPI protocol. The MCP492X operates from 2.7V ...
Page 17
Circuit Descriptions 4.1.1 OUTPUT AMPLIFIERS The DACs’ outputs are buffered with a low-power, precision CMOS amplifier. This amplifier provides low offset voltage and low noise. The output stage enables the device to operate with output voltages close to the ...
