概述

Description

AD8220BRMZ-R7 is Analog Devices’ instrumentation amplifier (IA). It provides precise differential amplification of small sensor signals with high common‑mode rejection. Gain is adjustable with an external RG resistor, and a REF pin lets you level‑shift the output to a chosen reference. The part comes in an 8‑lead surface‑mount package (BRMZ); the -R7 suffix indicates reel packaging for manufacturing.
Common applications: bridge sensors (load cells), RTDs/thermocouples, medical and industrial sensing.
Key usage notes: operate from a suitable supply (single or dual), connect +IN/−IN to the sensor, use RG to set the desired gain, tie REF to your reference level, and take the amplified signal from OUT. For exact gain ranges, bandwidth, offset, bias current, and CMRR specs, consult the AD8220 data sheet and packaging details for BRMZ-R7.

Features

AD8220BRMZ-R7 is a precision instrumentation amplifier in a compact BRMZ package. Key features include:
- RG-programmable gain from a few to high multiples
- Three-op-amp instrumentation amplifier core for high accuracy
- Very low input offset voltage and low drift
- Low input bias currents and low-noise performance
- High common-mode rejection ratio (CMRR) for accurate differential sensing
- Wide supply range with single-supply or dual-supply operation
- Wide bandwidth/gain-bandwidth performance suitable for sensor interfaces
- Robust common-mode input range and stable operation over temperature
- Compact, industry-standard packaging (BRMZ)
Note: for exact electrical specs (numbers), consult the AD8220 datasheet and the BRMZ-R7 package documentation.

Package

An 8-pin MSOP package (MSOP-8), RoHS-compliant.

Pinout

- Pin count: 8 pins (MSOP-8 package, BRMZ RoHS variant).
- Function: Instrumentation Amplifier. It amplifies the differential input signal with gain set by RG, provides a single-ended output, and includes a REF pin for output level shifting.
