CS5102A-JLZ

Analog To Digital Converters (ADC) Overview

The CS5102A-JLZ is a 16-bit monolithic CMOS analog-to-digital converter (ADC) from Cirrus Logic Inc. It provides a throughput of 20 kSps and features an inherent sampling architecture with a 2-channel input multiplexer. The device operates on dual ±5V supplies and consumes 44 mW in active mode, dropping to 1 mW in sleep mode. Key performance metrics include a signal-to-noise ratio of 90 dB, total harmonic distortion of 0.001%, and linearity error of ±0.001% FS. It utilizes self-calibration to maintain accuracy over time and temperature.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix JLZ against the manufacturer's ordering information to confirm package type and temperature range. Confirm RoHS compliance status for the current production batch. Check for end-of-life notices or alternative component recommendations from the manufacturer.

Analog To Digital Converters (ADC) Selection Notes

Select the CS5102A-JLZ when a low-power, high-precision 16-bit ADC is required for applications with moderate speed needs up to 20 kSps. Ensure the system supports dual ±5V analog and digital supplies. Consider the CS5101A if a higher throughput of 100 kSps is necessary, noting its significantly higher power consumption.

Analog To Digital Converters (ADC) Part Context

The CS5102A belongs to the CS5101A/CS5102A family of 16-bit A/D converters. While sharing similar architectural features and pinouts, the CS5102A is optimized for lower power and slower conversion speeds compared to the CS5101A. The JLZ suffix typically denotes a specific package variant and industrial temperature range.

Analog To Digital Converters (ADC) Replacement Considerations

No direct public substitute part numbers are listed in the provided documentation. Designers may evaluate other 16-bit sigma-delta ADCs from Cirrus Logic or competitors, ensuring compatibility with the ±5V supply requirement and serial interface timing.
