CS5507-ASZ

Analog To Digital Converters (ADC) Overview

The CS5507-ASZ is a single-channel, 16-bit analog-to-digital converter (ADC) from Cirrus Logic. It utilizes delta-sigma charge-balance conversion architecture with an on-chip digital filter and self-calibration circuitry. The device supports differential inputs and offers selectable unipolar or bipolar input ranges. It operates with low power consumption, requiring 1.7 mW at +5 V single supply or 3.2 mW at ±5 V dual supplies. The ADC provides output update rates up to 100 Sps and features a flexible serial interface compatible with industry-standard microcontrollers.

Analog To Digital Converters (ADC) Feature Summary

• 16-bit resolution with linearity error of ±0.0015% FS
• Single-channel differential analog input
• On-chip self-calibration for offset and gain accuracy
• Low power consumption: 1.7 mW (+5V) / 3.2 mW (±5V)
• Flexible serial port interface

Analog To Digital Converters (ADC) Applications

• Measurement of low-frequency physical signals
• Chemical process monitoring
• Biological signal acquisition

Analog To Digital Converters (ADC) Procurement Notes

Verify the -A suffix indicates the industrial temperature range (-40°C to +85°C). Confirm package type matches system requirements. Check current availability status as older CMOS components may have limited stock. Ensure voltage reference connections align with internal or external reference configurations specified in the datasheet.

Analog To Digital Converters (ADC) Selection Notes

Select the CS5507-ASZ for applications requiring high precision DC measurements with low power constraints. Compare against CS5508 if 20-bit resolution is needed. Consider the CS5505/CS5506 family if multiple pseudo-differential channels are required instead of a single channel. Verify clock frequency compatibility with the 32.768 kHz crystal or external clock options.

Analog To Digital Converters (ADC) Part Context

The CS5507-ASZ belongs to the CS5505/6/7/8 family of very low power CMOS A/D converters. This family includes 16-bit (CS5505/7) and 20-bit (CS5506/8) variants. The CS5507 specifically provides a single-channel version of the 16-bit architecture, distinguishing it from the four-channel CS5505.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements within the same family include the CS5507-AHZ or CS5507-SZ depending on temperature grade and package variations. For higher resolution needs, the CS5508 series serves as the 20-bit counterpart.
