CS5530-ISZR

Analog To Digital Converters (ADC) Overview

The CS5530-ISZR is a 24-bit delta-sigma analog-to-digital converter (ADC) featuring an integrated chopper-stabilized instrumentation amplifier with a fixed gain of 64X. It achieves ultra-low noise performance, specified at 12 nV/√Hz at 0.1 Hz, and offers up to 19 bits of noise-free resolution. The device supports selectable output word rates ranging from 6.25 to 3840 Sps and includes onboard offset and gain calibration registers. It utilizes a three-wire serial interface compatible with SPI and Microwire protocols.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ISZR suffix against current manufacturer documentation to confirm package type and reel specifications. Confirm RoHS compliance status and lead times directly with authorized distributors or Cirrus Logic, as availability may vary by region.

Analog To Digital Converters (ADC) Selection Notes

Select this component when low-level signal amplification and high-resolution conversion are required in a single package. Ensure the system clock frequency matches the required output word rate settings. Verify that the supply voltage configurations align with the application's power constraints.

Analog To Digital Converters (ADC) Part Context

The CS5530 belongs to the Cirrus Logic CS553x series of high-precision ADCs. The ISZR variant specifically denotes the industrial temperature range (-40°C to +85°C) and tape-and-reel packaging format, distinguishing it from tube-packaged versions like the CS5530-ISZ.

Analog To Digital Converters (ADC) Replacement Considerations

Consult official substitution guides for pin-compatible alternatives within the CS553x family or newer generations. Verify electrical parameter compatibility, particularly noise performance and supply voltage requirements, before implementing any cross-reference.
