CS5102A-BLZ

Analog To Digital Converters (ADC) Overview

The CS5102A-BLZ is a 16-bit monolithic CMOS analog-to-digital converter (ADC) from Cirrus Logic. It features an inherent sampling architecture with a 2-channel input multiplexer and flexible serial output port. The device delivers ultra-low distortion with a signal-to-noise-plus-distortion ratio of 92 dB and total harmonic distortion of 0.001%. It operates at a throughput of 20 kSps with a conversion time of 40 µs. On-chip self-calibration maintains accuracy over time and temperature, ensuring no missing codes. Power consumption is 44 mW, supporting battery-powered applications.

Analog To Digital Converters (ADC) Procurement Notes

Verify the BLZ suffix indicates RoHS compliance and halogen-free status per Cirrus Logic standards. Confirm the package type matches system board requirements, as this part typically uses PLCC or similar leaded packages depending on specific sub-variants. Check for end-of-life notices or obsolescence announcements from the manufacturer before finalizing procurement plans.

Analog To Digital Converters (ADC) Selection Notes

Select the CS5102A-BLZ when a 20 kSps sampling rate is sufficient for the application. Choose this model over the CS5101A variant if lower power consumption (44 mW vs 320 mW) is critical. Ensure the system can provide dual ±5V analog supplies and a master clock up to 1.6 MHz for optimal performance in FRN mode.

Analog To Digital Converters (ADC) Part Context

The CS5102A belongs to the CS5101A/CS5102A family of 16-bit ADCs. While the CS5101A offers 100 kSps throughput, the CS5102A is optimized for lower speed and significantly reduced power dissipation. Both share identical pinouts and calibration architectures, allowing for potential design flexibility between high-speed and low-power implementations within the same product line.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional replacements include the CS5101A if higher speed is acceptable and power budget allows. For legacy support, verify compatibility with older Cirrus Logic 16-bit ADCs like the CS5102. No direct modern equivalents are listed in the provided documentation; check for newer sigma-delta alternatives if PLCC packaging is no longer viable.
