CS5451A-ISZR

Analog To Digital Converters (ADC) Overview

The CS5451A-ISZR is a six-channel delta-sigma analog-to-digital converter (ADC) manufactured by Cirrus Logic. It features a 16-bit resolution and utilizes an SPI serial interface for data communication. The device supports differential input signals and includes both external and internal reference options. Designed for surface-mount installation in a TSSOP-24 package, it operates within a temperature range of -40°C to +85°C. The component dissipates up to 500 mW of power and integrates six independent converters on a single chip.
