CS5516-ASZ

Analog To Digital Converters (ADC) Overview

The CS5516-ASZ is a monolithic CMOS analog-to-digital converter featuring a 16-bit delta-sigma modulator. It integrates an instrumentation amplifier with fixed gain of 25, a programmable gain amplifier (PGA) with selectable gains of 1, 2, 4, or 8, and a 4-bit DAC for offset trimming. The device operates on dual ±5V supplies and supports serial communication via a 3-, 4-, or 5-wire interface. It achieves a linearity error of ±0.0015% FS with no missing codes and includes system calibration capabilities to null offset and gain errors.

Analog To Digital Converters (ADC) Feature Summary

• Integrated instrumentation amplifier with fixed gain of 25 and software-selectable PGA gains (1x, 2x, 4x, 8x).
• On-chip 4-bit D/A converter for coarse offset removal and system calibration support.
• Dynamic excitation options supporting DC or AC bridge excitation with demodulation.
• High common-mode rejection ratio (CMRR > 200 dB at 50/60 Hz).

Analog To Digital Converters (ADC) Applications

• Digitizing low-level signals from strain gauges.
• Signal acquisition from load cells.
• Pressure transducer interfacing.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'ASZ' against current manufacturer documentation to confirm package type and temperature range, as ordering suffixes define physical attributes. Confirm availability status, as legacy components may be subject to end-of-life notices or production changes.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring ratiometric measurement of Wheatstone bridge transducers. Ensure the design accommodates dual ±5V power supplies and utilizes external clock sources or crystals within the 1.0 MHz to 5.0 MHz range for optimal performance.

Analog To Digital Converters (ADC) Part Context

The CS5516-ASZ belongs to the CS5516/CS5520 family of bridge transducer A/D converters. While the CS5520 variant offers 20-bit resolution, the CS5516 provides 16-bit resolution. Both share identical internal architectures, including the instrumentation amplifier, PGA, and calibration microcontroller.
