AD8556ARZ-REEL

Overview

The AD8556ARZ-REEL is a zero-drift sensor signal amplifier with digitally programmable gain and output offset. It operates from single-supply voltages of 4.5 V to 5.5 V. The device features a maximum input offset voltage of 10 µV and a drift of 65 nV/°C. Common-mode rejection ratio is 94 dB minimum. Gain is digitally programmable from 70 to 1280 via a serial interface. Supply current is typically 2.7 mA. The component is housed in an 8-lead SOIC_N package.

Feature Summary

• Digitally programmable gain ranging from 70 to 1280 through a single-wire serial interface
• Integrated EMI filters on input pins and power supply lines
• Built-in open and short wire fault detection capabilities
• Programmable output clamp voltage for safe ADC interfacing

Applications

• Pressure sensors
• Position sensors
• Precision current sensing
• Strain gages

Procurement Notes

Verify the specific suffix ARZ indicates the RoHS-compliant SOIC_N package variant. Confirm the REEL designation matches the required tape-and-reel quantity for production integration. Ensure the ordering code aligns with the manufacturer's current documentation to avoid obsolete or discontinued stock issues.

Selection Notes

Select this component when high precision is required for bridge sensor signals. The zero-drift technology minimizes calibration needs over temperature. Verify that the digital programming interface fits the system architecture. Ensure the 4.5 V to 5.5 V supply range matches the available power rails.

Part Context

This part belongs to the AD8556 family of sensor signal amplifiers. It utilizes auto-zero and DigiTrim technologies for accuracy. The series includes variants like the AD8557. The device is designed for compact footprints while maintaining high DC and AC CMRR performance in industrial environments.

Replacement Considerations

Check for AD8556ACPZ-R2 if LFCSP_WQ packaging is required instead of SOIC_N.
