概述

Description

ADA4625-2ARDZ-R7 is a dual, zero-drift precision op-amp from Analog Devices, packaged in an ARDZ (8‑lead) RoHS-compliant package with tape-and-reel option (-R7). It combines two chopper/stabilized amplifiers in one device for high-accuracy signal conditioning.
Key points:
- Dual precision op-amps with ultra-low offset and drift, suitable for high-accuracy instrumentation.
- Very low input bias current and low noise for delicate sensor and transimpedance applications.
- Rail-to-rail output on likely single-supply operation, with stable performance over temperature.
- Ideal for instrumentation front-ends, bridge sensors, ADC drivers, and precision gain stages.
- Packaging: ARDZ, -R7 denotes packaging/reel option; RoHS-compliant.
For exact electrical specs (input offset, drift, bias current, noise, gain bandwidth, and supply range), refer to the ADA4625-2 datasheet and product page.

Features

- Dual, precision op-amp pair (two channels) with chopper-stabilized, zero-drift architecture for high accuracy
- Ultra-low input offset voltage and very low drift over temperature
- Very low input bias current
- Rail-to-rail input and output for single-supply operation
- Low-noise performance suitable for precision sensor conditioning
- Wide supply voltage range with low quiescent current
- Good PSRR and CMRR for robust accuracy in varying supply and common-mode conditions
- Suitable for instrumentation and DC/low-frequency signal conditioning
- 8-lead LFCSP package (ARDZ), RoHS-compliant (R7 denotes package/affiliates)

Package

It’s in an 8‑lead MSOP (DMSOP) RoHS package, shipped in tape‑and‑reel (R7).

Pinout

- Pin count: 8 pins
- Function: Dual operational amplifier (two op-amp channels) in one package (ADA4625-2).

Manufacturer

- Manufacturer: Analog Devices, Inc. (ADI)
- Company type: Global semiconductor company that designs and manufactures analog, mixed-signal, and DSP integrated circuits for various industries (industrial, automotive, communications, consumer electronics).

Application

ADA4625-2ARDZ-R7 is a dual, precision, low-noise, zero-drift op-amp. Typical applications:
- Sensor front-ends (bridge sensors, RTDs, strain gauges)
- Transimpedance amplifiers for photodiodes
- ADC input buffers and precision instrumentation front-ends
- Medical instrumentation and patient-monitoring equipment
- Portable, battery-powered instrumentation
- Automotive/industrial sensor interfaces requiring low offset and drift
