CS5524-ASZR

Analog To Digital Converters (ADC) Overview

The CS5524-ASZR is a four-channel, 24-bit analog-to-digital converter (ADC) from Cirrus Logic. It utilizes a fourth-order delta-sigma architecture with an integrated chopper-stabilized instrumentation amplifier and programmable gain amplifier (PGA). The device supports input spans ranging from 25 mV to 5 V and operates on a single +5 V supply. Key specifications include a maximum sampling rate of 617 Sps with a 200 kHz clock, low power consumption of 6.0 mW in normal mode, and a three-wire serial interface compatible with SPI and Microwire protocols.

Analog To Digital Converters (ADC) Feature Summary

• 24-bit resolution with four differential inputs and integrated PGA
• Fourth-order delta-sigma modulator with digital filter for 50/60 Hz rejection
• Three-wire serial interface (SPI/Microwire compatible) with FIFO buffer
• Integrated charge pump drive for negative bias voltage generation

Analog To Digital Converters (ADC) Applications

• Process control systems requiring high-precision signal measurement
• Ground-based thermocouple monitoring applications
• Low-level isolated and non-isolated signal acquisition

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against current manufacturer documentation to confirm package type and environmental compliance. Check for product change notices regarding obsolescence or pin label standardization updates prior to finalizing procurement plans.

Analog To Digital Converters (ADC) Selection Notes

Select the CS5524-ASZR when four independent channels are required within a single package. Ensure the external reference voltage falls within the 1 V to 5 V range. Confirm that the system clock frequency supports the desired output word rate, noting that higher speeds require clocks up to 200 kHz.

Analog To Digital Converters (ADC) Part Context

This component belongs to the CS552x family of highly integrated ADCs. The CS5524 specifically provides four channels, distinguishing it from the two-channel CS5521/22 and eight-channel CS5528 variants. All members share the same core delta-sigma architecture and peripheral features.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional substitutes within the same family include the CS5523 (16-bit version) or CS5528 (eight-channel version), provided pin compatibility and channel count requirements align with the design constraints.
