ADC10158CIWM

Analog To Digital Converters (ADC) Overview

The ADC10158CIWM is a 10-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features an internal multiplexer supporting 4 or 8 channels, a track-and-hold circuit, and an integrated reference. The device operates on a single 4.5 V to 5.5 V supply for both analog and digital domains. It delivers a sampling rate of 227 kS/s with a parallel interface. Key performance metrics include a gain error of 1.5 LSB and integral nonlinearity (INL) of 1 LSB. The component is housed in a 28-pin SOIC package and functions within a temperature range of -40°C to +85°C.
