CS5534-BSZ

Analog To Digital Converters (ADC) Overview

The CS5534-BSZ is a 24-bit sigma-delta analog-to-digital converter (ADC) from Cirrus Logic, housed in a 24-pin SSOP package. It features four differential inputs and an integrated chopper-stabilized programmable gain instrumentation amplifier (PGIA) with gains ranging from 1x to 64x. The device utilizes a three-wire serial interface compatible with SPI and Microwire standards. Key electrical specifications include a maximum sampling rate of 3,840 S/s, an integral non-linearity of +/- 0.0015% FSR, and a reference voltage of 2.5 V. It operates within a temperature range of -40°C to +85°C and has a power dissipation of 500 mW.

Analog To Digital Converters (ADC) Feature Summary

• Four-channel differential input multiplexer with ultra-low noise PGIA
• Chopper stabilization eliminates 1/f noise for high precision
• Integrated calibration registers per channel for scalability
• Selectable line rejection for 50 Hz or 60 Hz applications

Analog To Digital Converters (ADC) Applications

• Weigh scales and strain gauge measurements
• Industrial process control systems
• Scientific instrumentation
• Medical equipment requiring high-resolution signal acquisition

Analog To Digital Converters (ADC) Procurement Notes

The CS5534-BSZ is designated as obsolete by the manufacturer, indicating end-of-life status. Availability is restricted, and distributors may not stock this item in all regions. Verification of current lifecycle status and alternative sourcing options is required before procurement planning.

Analog To Digital Converters (ADC) Selection Notes

Select the CS5534-BSZ for applications requiring four independent channels with high resolution and low noise. Ensure the design supports the required 2.5 V reference voltage and 3V to 5V digital supply. Verify that the system can accommodate the SSOP-24 package dimensions and thermal requirements associated with 500 mW power dissipation.

Analog To Digital Converters (ADC) Part Context

This component belongs to the CS5534 series of highly integrated delta-sigma ADCs. It shares architectural similarities with other members like the CS5532 and CS5533 but offers four channels compared to two in the CS5532. The 'BSZ' suffix denotes the specific package type and RoHS compliance status within the Cirrus Logic product lineup.
