MCP4911-E/MS

MCP4911-E/MS is a 10bit voltage output digital-to-analogue converter with SPI interface. The device operates from a single 2.7V to 5.5V supply with an SPI compatible serial peripheral interface. The user can configure the full-scale range of the device to be VREF or 2*VREF by setting the gain selection option bit (gain of 1 of 2). The user can shut down the device by setting the configuration register bit. In shutdown mode, most of the internal circuits are turned off for power savings, and the output amplifier is configured to present a known high resistance output load (500Kohm, typical). The device includes double-buffered registers, allowing synchronous updates of the DAC output using the LDAC pin. Application includes set point or offset trimming, precision selectable voltage reference, motor control feedback loop, digitally-controlled multiplier/divider, calibration of optical communication devices.
