CS5529-ASZR

Analog To Digital Converters (ADC) Overview

The CS5529-ASZR is a 16-bit, low-power programmable delta-sigma analog-to-digital converter (ADC) manufactured by Cirrus Logic Inc. It features a fourth-order modulator, eight selectable digital filters, and a 6-bit output latch. The device supports single or dual analog supplies with a nominal 2.5 V input range. Key electrical parameters include a linearity error of ±0.0015% FS, noise-free resolution of 16 bits, and power consumption of 2.6 mW in normal mode. Output word rates are configurable between 1.88 Sps and 101 Sps using a 32.768 kHz clock. It utilizes a three-wire serial interface compatible with SPI and Microwire standards.

Analog To Digital Converters (ADC) Feature Summary

• 16-bit resolution with 0.0015% FS linearity error and no missing codes
• Programmable digital filters offering eight output word rates from 1.88 to 101 Sps
• Integrated 6-bit output latch for isolated data acquisition systems
• Simultaneous 50 Hz and 60 Hz rejection at output rates ≤ 15 Sps

Analog To Digital Converters (ADC) Applications

• Isolated and non-isolated industrial data acquisition systems
• Low-power sensor interfaces requiring high linearity
• Applications necessitating galvanic isolation between analog and digital domains

Analog To Digital Converters (ADC) Procurement Notes

Verify the component status as Last Time Buy or End of Life through official Cirrus Logic channels before finalizing procurement plans. Confirm that the ASZR suffix corresponds to the tape-and-reel packaging format required for surface-mount assembly processes. Ensure supply chain continuity strategies are in place given the product's lifecycle stage.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution with high linearity is required alongside integrated isolation capabilities via the 6-bit latch. Verify that the system clock frequency matches the desired output word rate, noting that a 100 kHz clock increases throughput approximately threefold compared to the standard 32.768 kHz crystal. Ensure the analog supply configuration aligns with the bipolar or unipolar input requirements.

Analog To Digital Converters (ADC) Part Context

The CS5529 belongs to the Cirrus Logic CS55xx series of precision ADCs. It is specifically designed for applications where digital isolation is critical, leveraging its internal latch to hold conversion data while the serial interface communicates asynchronously. This distinguishes it from standard sigma-delta ADCs that require continuous clocking during data readout.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative Cirrus Logic ADCs within the same family for pin compatibility and functional equivalence if sourcing becomes unavailable.
