CS5550K-ISZR

Analog To Digital Converters (ADC) Overview

The CS5550K-ISZR is a dual-channel, low-cost analog-to-digital converter (ADC) from Cirrus Logic. It integrates two delta-sigma modulators and a serial interface on a single chip. The device features adjustable input ranges for AIN1±, supporting GND-referenced signals with a single supply. An on-chip 2.5 V reference with a typical temperature coefficient of 25 ppm/°C is included. Power consumption is less than 12 mW with VD+ at 3.3 V. The component operates within a temperature range of -40°C to +85°C and is housed in a 24-pin SSOP package.
