AMC1203PSA

Analog To Digital Converters (ADC) Overview

The AMC1203PSA is a high-precision, isolated sigma-delta analog-to-digital converter manufactured by Texas Instruments. It features a 16-bit resolution and operates with a sampling rate of 40 kS/s. The device utilizes a second-order delta-sigma modulation architecture to achieve high linearity and noise performance. It supports differential input signals and communicates via a serial interface. The component requires external power supplies ranging from 4.5 V to 5.5 V for both analog and digital domains. It is housed in an SOIC-16 surface-mount package and is rated for operation within a temperature range of -40°C to +105°C.
