CS5512-BSZR

Analog To Digital Converters (ADC) Overview

The CS5512-BSZR is a 20-bit delta-sigma analog-to-digital converter (ADC) from Cirrus Logic, housed in an 8-pin SOIC package. It utilizes charge-balance techniques to achieve high precision with a linearity error of ±0.0015% FS and up to 17 noise-free bits. The device features differential bipolar analog inputs and supports a voltage reference range from 250 mV to 5 V. Designed for industrial applications such as weigh scales and process control, it offers simultaneous 50/60 Hz line rejection and operates at output word rates between 16 and 326 Sps. Power consumption is low, drawing 1.8 mW in normal mode and 10 µW in sleep mode.

Analog To Digital Converters (ADC) Procurement Notes

Verify the component status before procurement, as distribution sources indicate this part may be obsolete or end-of-life. Confirm the specific suffix 'Z' corresponds to lead-free packaging requirements if applicable to your manufacturing standards. Ensure compatibility with existing PCB footprints for the 8-pin SOIC package.

Analog To Digital Converters (ADC) Selection Notes

Select the CS5512-BSZR when 20-bit resolution and simultaneous 50/60 Hz rejection are required without an external oscillator. Unlike the CS5511/13 variants, this model requires an external master clock on the SCLK pin. Ensure the supply configuration matches the application's common-mode voltage needs, supporting both single +5V and dual-supply arrangements.

Analog To Digital Converters (ADC) Part Context

This component belongs to the CS5510/11/12/13 family of low-cost, space-efficient ADCs. The CS5512 variant specifically provides 20-bit performance, distinguishing it from the 16-bit CS5510/11 models. It shares the same 8-pin SOIC footprint and general interface characteristics with its siblings but relies on external clocking rather than an internal oscillator.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should evaluate alternative 20-bit delta-sigma ADCs from other manufacturers if this component is discontinued, ensuring similar pinout and electrical specifications.
