Description
The MAX14972CTG+T is a low-power analog-to-digital converter (ADC) with integrated LED drivers. It operates from a single 2.7V to 5.25V power supply and includes an internal reference, a high-accuracy oscillator, and a multiplexed LED display driver. The ADC is configurable for either a ±2V or ±200mV input range and outputs its conversion results to an LED and/or a microcontroller (µC). Microcontroller communication is possible through an SPI™-/QSPI™-/MICROWIRE™-compatible serial interface. The MAX14972CTG+T is available in a small 32-pin, 7mm x 7mm TQFP package.
