概述

Description

AD8429ARZ-R7 is Analog Devices’ high-precision instrumentation amplifier (in-amp) in an 8-lead package. It provides externally gain-set amplification of small differential sensor signals with three integrated op-amps, delivering low offset, low noise, and strong common-mode rejection over a wide supply range. It’s ideal for bridge sensors, strain gauges, load cells, thermocouples, and biomedical sensing where accuracy is critical. ARZ indicates the 8-lead LFCSP package; -R7 denotes Tape & Reel packaging. For exact specs (gain range via RG, supply voltages, input/output range, bandwidth, and noise), consult the AD8429 datasheet and application notes.

Features

Here are the key features of the AD8429ARZ-R7 (concise):
- Precision instrumentation amplifier (3-op-amp core) with RG-settable gain
- Ultra-low input offset voltage and drift; high CMRR over temperature
- Very low input bias current for high-impedance sensors
- Wide supply voltage range; suitable for single- or dual-supply operation
- Low-noise performance with good bandwidth
- Low power consumption
- Robust input protection and ESD robustness
- Industrial-temperature operation
- RoHS-compliant package (ARZ)
Note: For exact electrical specs (offset, noise, gain range, CMRR values, bandwidth, and supply voltages), refer to the official AD8429 datasheet.

Package

Package type: 8‑lead MSOP (MSOP‑8) in tape‑and‑reel packaging. The -R7 indicates a 7‑inch reel.

Pinout

- Pin count: 8 pins
- Function: An 8‑pin instrumentation amplifier (AD8429) with three internal op‑amps; provides differential input amplification with high CMRR and a single-ended output. Gain is set by an external RG resistor. Used for precise, low-noise differential measurements.

Manufacturer
