ADC10738CIWM/NOPB

Analog To Digital Converters (ADC) Overview

The ADC10738CIWM/NOPB is a CMOS 10-bit signed successive approximation analog-to-digital converter manufactured by Texas Instruments. It features an integrated multiplexer supporting eight input channels, which can be configured for single-ended or differential operation via software control. The device includes a built-in 2.5V bandgap reference with ±2% accuracy and incorporates sampling/holding capabilities. It operates on a single 5V supply, consuming a maximum of 37mW during normal conversion and reducing to 18μW in power-down mode. The component utilizes a MICROWIRE-compatible serial interface for data exchange.
