CS5529-ASZ

Analog To Digital Converters (ADC) Overview

The CS5529-ASZ 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, coarse/fine charge buffers, and an integrated calibration microcontroller. The device supports single or dual analog supply configurations with digital supplies ranging from 3V to 5V. Key electrical specifications include a linearity error of ±0.0015%FS, noise-free resolution of 16 bits, and selectable output word rates 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 simultaneous 50/60 Hz rejection at rates ≤15 Sps
• Programmable digital filters offering eight output word rates from 1.88 Sps to 101 Sps
• Integrated 6-bit output latch and system/self-calibration capabilities via R/W registers
• Low power consumption of 2.6 mW in normal mode with support for bipolar/unipolar inputs

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring isolated or non-isolated signal digitization
• Weighing scales and load cell measurement applications
• Temperature monitoring systems utilizing thermocouples or RTDs
• Pressure transducer interfaces

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'ASZ' against the manufacturer's current ordering information to confirm package type and lead-free status. Confirm that the component meets RoHS compliance requirements for the intended market. Check for any End-of-Life notifications or Product Change Notices affecting this specific part number before finalizing procurement plans.

Analog To Digital Converters (ADC) Selection Notes

Select the CS5529-ASZ when a high-precision, low-speed ADC with built-in calibration is required. Ensure the application can accommodate the external 32.768 kHz crystal oscillator or provide an external clock source up to 100 kHz. Verify that the analog input range matches the available bipolar (+/-2.5V) or unipolar (0-5V) supply configurations. Consider the 20-SSOP package dimensions for PCB layout constraints.

Analog To Digital Converters (ADC) Part Context

The CS5529 belongs to Cirrus Logic's family of precision delta-sigma ADCs designed for industrial sensor interfaces. It shares architectural similarities with other models like the CS5525 and CS5511 but offers specific filter characteristics and a 6-bit latch feature. This component is distinct from audio DACs like the CS4353 or operational amplifiers like the CS3012 within the same manufacturer portfolio.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative Cirrus Logic ADCs such as the CS5525 or CS5511 based on pin compatibility and performance requirements, ensuring full functional verification if cross-referencing.
