Overview
The ADCS7477AIMF/NOPB is a low-power, monolithic CMOS analog-to-digital converter (ADC) produced by Texas Instruments. This device is part of the ADCS747x series, which includes 12-bit, 10-bit, and 8-bit ADCs. The ADCS7477 specifically is a 10-bit ADC that operates at a conversion rate of 1 MSPS (mega-samples per second). It is designed to be a drop-in replacement for Analog Devices' AD747x series and features a successive approximation register architecture with an internal track-and-hold circuit.
The device is packaged in a 6-pin SOT-23 package and operates on a single supply voltage ranging from 2.7 V to 5.25 V, which also serves as the reference voltage. The ADCS7477 is compatible with various serial interfaces, including SPI, QSPI, MICROWIRE, and many common DSP serial interfaces.
