Description

AD8222ACPZ-R7 is Analog Devices’ precision instrumentation amplifier in an 8‑lead plastic package (ACPZ). It amplifies small differential sensor signals while rejecting common-mode voltages, providing high input impedance and low offset/drift with low noise. Gains are externally programmable via RG, making it suitable for bridge sensors (e.g., load cells), medical instrumentation, and other precision sensor conditioning in battery-powered or compact systems. It supports single-supply operation and typically offers good CMRR and rail-to-rail output performance under common loading. The “-R7” denotes the reel/tape packaging variant, while “ACPZ” specifies the RoHS-compliant plastic package.

Features

Key features of AD8222ACPZ-R7:
- Precision instrumentation amplifier with RG-set Gain for a wide range of gains
- External reference pin for output level shifting
- Differential input with high CMRR and excellent PSRR
- Wide supply range (suitable for single or dual supply applications)
- Low input bias current and low input offset voltage with low drift
- Low noise performance suitable for precision sensing
- Road-tested protection: input overload/short-circuit protection
- Output can be driven close to rails (rail-to-rail output behavior on many ranges)
- Small 8-lead LFCSP package (ACPZ) suitable for compact designs
- Stable operation over a broad temperature range
Note: For exact electrical specs (gain range, CMRR numbers, supply limits, etc.), refer to the AD8222 datasheet.

Package
