CS5506-BSZ

Analog To Digital Converters (ADC) Overview

The CS5506-BSZ is a 20-bit analog-to-digital converter (ADC) from the Cirrus Logic CS5505/6/7/8 family. It features four pseudo-differential analog input channels and utilizes a delta-sigma architecture with an on-chip digital filter. The device operates with single +5V or dual ±5V supplies, consuming as little as 1.7 mW in single-supply mode. It supports output update rates up to 100 Sps and includes self-calibration circuitry for offset and gain accuracy. The serial interface allows direct connection to microcontrollers.

Analog To Digital Converters (ADC) Feature Summary

• 20-bit resolution with linearity error of ±0.0007% FS
• Four-channel pseudo-differential analog inputs
• Very low power consumption: 1.7 mW at +5V single supply
• On-chip self-calibration and digital filter with 50/60 Hz rejection

Analog To Digital Converters (ADC) Applications

• Measurement of low-frequency physical, chemical, and biological signals
• Industrial process control systems requiring high precision
• Weigh scales and load cell interfaces
• Bridge sensor measurements

Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity through authorized distributors. Check datasheet revision DS59F7 for current specifications. Confirm package type SSOP-24 matches design requirements. Ensure voltage reference and clock source connections align with recommended operating conditions.

Analog To Digital Converters (ADC) Selection Notes

Select CS5506-BSZ for applications requiring 20-bit resolution and multiple input channels. Choose CS5508 if only a single channel is needed. Ensure external clock frequency is between 30 kHz and 163 kHz. Verify that supply voltages remain within specified limits for analog and digital sections.

Analog To Digital Converters (ADC) Part Context

Part of the CS5505/6/7/8 family of very low power A/D converters. The CS5506 specifically provides four channels with 20-bit resolution, distinguishing it from the 16-bit CS5505 and single-channel variants CS5507/8.

Analog To Digital Converters (ADC) Replacement Considerations

CS5508-BSZ offers identical performance but with a single differential input channel instead of four. CS5506-ASZ may be available with different temperature grading or packaging options.
