CS5525-ASZ

Analog To Digital Converters (ADC) Overview

The CS5525-ASZ is a 16-bit, single-channel delta-sigma analog-to-digital converter (ADC) manufactured by Cirrus Logic. It integrates a chopper-stabilized instrumentation amplifier, programmable gain amplifier (PGA), and digital filters. The device supports bipolar and unipolar input ranges from 25 mV to 5 V with a linearity error of ±0.003% FSR. It operates on a single +5 V analog supply and a +3.0 V or +5 V digital supply. Key features include simultaneous 50/60 Hz noise rejection, self-calibration capabilities, and a simple three-wire serial interface compatible with SPI and Microwire standards.

• Medical instrumentation applications

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'ASZ' against the manufacturer's current ordering information to confirm package type and environmental compliance status. Check for End-of-Life notifications as older Cirrus Logic components may have limited availability or replacement recommendations.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a high-resolution, low-noise ADC with integrated front-end amplification is required. Ensure the application can accommodate the external charge pump circuitry if measuring ground-referenced bipolar signals below ±100 mV. Verify that the required output data rate falls within the supported range of 3.76 Sps to 616 Sps based on the crystal frequency.

Analog To Digital Converters (ADC) Part Context

The CS5525 is part of the CS5525/CS5526 family, which are pin-compatible 16-bit and 20-bit converters. It shares architectural similarities with other Cirrus Logic precision ADCs like the CS5532 series but offers different resolution and integration levels. The 'ASZ' suffix typically denotes a specific package variant and temperature range within the product line.

Analog To Digital Converters (ADC) Replacement Considerations
