Product details

Zero-drift precision amp rated to 140°C

The AD8556ACPZ-R2 is a single-channel zero-drift amplifier from ADI's DigiTrim® series, packaged in a 16-lead LFCSP-VQ (4x4 mm) with exposed pad. Its chopper-stabilized topology delivers a 2 µV typical input offset voltage and 49 nA input bias current.

140°C operating range — where it earns its keep

The -40°C to 140°C temperature grade is the standout differentiator. Most zero-drift amplifiers in this class — including the AD8557 family — are rated to 125°C maximum.

Supply and output — single 5 V rail, 10 mA drive

The output can source or sink 10 mA per channel.

Frequently asked questions

Is AD8556ACPZ-R2 equivalent to AD8555?

No direct equivalence is documented. The AD8555 is a different DigiTrim® variant with programmable gain; the AD8556 is a fixed-gain zero-drift amplifier. Verify pinout and function before substituting.
