MCP33131D-05-E/MS

MCP33131D-05-E/MS is a differential input SAR ADC. It features low power consumption and high performance, using a successive approximation register (SAR) architecture. The device operates with a 2.5V to 5.1V external reference (VREF), which supports a wide range of input full-scale range from -VREF to +VREF. The reference voltage setting is independent of the analog supply voltage (AVDD) and is higher than AVDD. The conversion output is available through an easy-to-use simple SPI- compatible 3-wire interface. This device can be used for various high-speed and high-accuracy analog-to-digital data conversion applications, where design simplicity, low power, and no output latency are needed. Typical applications are high-precision data acquisition, medical instruments, test equipment, electric vehicle battery management systems, motor control applications, switch-mode power supply applications, battery-powered equipment.
