CS5513-BSR

Analog To Digital Converters (ADC) Overview

The CS5513-BSR is a low-cost, easy-to-use 20-bit Delta-Sigma analog-to-digital converter (ADC) from Cirrus Logic. It utilizes charge-balance techniques to achieve high precision in industrial applications such as weighing and process control. The device features a single differential input channel and operates within a supply voltage range of 4.75 V to 5.25 V. It supports a sampling rate of 326 samples per second and employs an SPI serial interface for data communication. Packaged in an 8-pin SOIC format, the component is designed for surface-mount installation.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a 20-bit Delta-Sigma architecture utilizing charge-balance conversion techniques for high-resolution signal processing.

Analog To Digital Converters (ADC) Applications

• Industrial weighing systems
• Process control instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify current availability status as the CS5513 family has been subject to discontinuation notices by the manufacturer. Confirm that the specific suffix 'BSR' matches the required tape-and-reel packaging configuration for automated assembly lines. Ensure compatibility with existing system power supplies and SPI bus protocols before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 20-bit resolution ADC is required for cost-sensitive industrial designs. The choice depends on the necessity for a 326 S/s sampling rate and the availability of an 8-pin SOIC footprint. Consider alternative package options if reel packaging is not preferred or if higher channel counts are needed.

Analog To Digital Converters (ADC) Part Context

This part belongs to the CS551x series of Delta-Sigma ADCs, which share common architectural features but differ in resolution and pin configurations. The CS5513 specifically provides 20-bit performance compared to the 16-bit CS5511 or the multi-channel variants like the CS5523. The 'BSR' suffix indicates a specific tape-and-reel packaging variant distinct from the tube-packaged 'BSZ'.

Analog To Digital Converters (ADC) Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The CS5513 family is listed under discontinued products by Cirrus Logic; verify end-of-life status and potential obsolescence risks before relying on this component for new designs.
