CS5507-ASZR

Analog To Digital Converters (ADC) Overview

The CS5507-ASZR is a low-power, single-channel, 16-bit analog-to-digital converter (ADC) manufactured by Cirrus Logic. It utilizes a delta-sigma architecture with an on-chip digital filter and self-calibration circuitry to ensure high accuracy. The device supports both unipolar and bipolar input ranges via pin selection and operates with either internal or external voltage references. It features a flexible serial interface compatible with industry-standard microcontrollers and offers output update rates up to 100 samples per second. Power consumption is minimized at 1.7 mW with a single +5 V supply.

Analog To Digital Converters (ADC) Feature Summary

• 16-bit resolution with linearity error of ±0.0015% FS
• Single differential analog input channel
• On-chip self-calibration for offset and gain accuracy
• Flexible serial port supporting SSC and SEC modes

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 transducer applications

Analog To Digital Converters (ADC) Procurement Notes

Verify the component status as the CS5507 series may be discontinued or in last-time buy phases. Confirm the -S suffix indicates the extended temperature range (-55°C to +125°C). Ensure the ZR suffix corresponds to the tape and reel packaging format required for automated assembly processes.

Analog To Digital Converters (ADC) Selection Notes

Select the CS5507-ASZR when a single-channel, 16-bit ADC with low power consumption is required. Choose this part over the CS5508 if 16-bit resolution suffices, as it offers lower power dissipation. Ensure the application requires a sampling rate up to 100 Sps and can accommodate the SPI-compatible serial interface timing constraints.

Analog To Digital Converters (ADC) Part Context

The CS5507 is part of the CS5505/6/7/8 family of very low power CMOS A/D converters. It shares architectural similarities with the four-channel CS5505 but provides only one differential input channel. This family is designed specifically for DC signal measurement where high linearity and low noise are critical.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should evaluate the CS5508 for 20-bit resolution requirements or the CS5505 for multi-channel needs within the same family.
