MCP4922T-E/ST

MCP4922T-E/ST is a 2.7 to 5.5V, low-power, low DNL, 12bit DAC in a plastic TSSOP package. Available with optional 2x buffered output and SPI interface. The MCP4922 DAC provides high accuracy and low noise performance for industrial applications where calibration or compensation of signals (such as temperature, pressure and humidity) are required. The MCP4922 device utilizes a resistive string architecture, with its inherent advantages of low DNL error, low ratio metric temperature coefficient and fast settling time. The MCP4922 include double buffered inputs, allowing simultaneous updates using the active low LDAC pin. This device also incorporates a Power-On Reset (POR) circuit to ensure reliable power-up. Typical applications include set point or offset trimming, sensor calibration, digitally-controlled multiplier/divider, portable instrumentation (battery-powered) and motor feedback loop control.
