Description

MCP4902 is a dual channel, 8-bit DAC with an external voltage reference and SPI interface. It offers high accuracy and low power consumption and is available in various packages. This device is a part of the MCP4902/MCP4912/MCP4922 product family, which are dual channel 8-bit/10-bit/12-bit DACs which use an external voltage reference (VREF). These devices provide very high accuracy and low noise performance, and are suitable for consumer and industrial applications, such as set point control, offset adjustment and sensor calibration applications. The low power consumption and small package options make these devices very attractive for many portable and battery-powered applications. If a single output is needed then the MCP4901/4911/4921 single channel product family can be used.
