Présentation

Description

AD8572AR is a dual operational amplifier from Analog Devices. It’s designed for precision signal conditioning in instrumentation, sensor interfaces, buffering, and active filter applications. The AR suffix indicates RoHS-compliant, lead-free packaging (often tape-and-reel). Key points: two high-precision op-amps with low input offset voltage and low bias current, suitable for single- or dual-supply use, and optimized for low drift and reasonable noise performance. Common use cases include buffering high-impedance sensors, summing/differencing amplifiers, integrators, and active filters. For exact specs (supply voltage range, input/output ranges, gain-bandwidth product, slew rate, offset, and noise) and packaging details, refer to the AD8572 datasheet and the AR variant documentation.

Equivalent

Do you need pin‑for‑pin cross references or just functionally similar parts? Please share the required specs (supply voltage, gain‑bandwidth product, input offset voltage, noise, package). With that, I can give precise equivalents from TI, Analog Devices, and others.

Features

AD8572AR features (dual op-amps in one package):
- Dual, general-purpose operational amplifiers
- Low noise and low input offset voltage for precise DC performance
- Unity-gain stable; suitable for closed-loop configurations
- High speed with ample slew rate and wide bandwidth for fast signals
- Wide supply voltage range; supports single-supply or dual-supply operation
- Good power-supply rejection (PSRR) and common-mode rejection (CMRR
- Stable with capacitive loads
- Available in compact 8-pin packages (e.g., MSOP-8/SOIC-8); RoHS-compliant (AR suffix)
Note: for exact numbers (GBW, slew rate, input bias, offset, and recommended operating ranges), please consult the AD8572AR datasheet.

Pinout

Pin count: 8 pins (dual package in common packages like SOIC/DIP).
Function: AD8572AR is a dual operational amplifier (two op-amps in one 8-pin package) for analog signal conditioning.

Manufacturer

- Manufacturer: Analog Devices, Inc. (ADI).
- What kind of company: A U.S.-based multinational semiconductor company that designs and manufactures high-performance analog, mixed-signal, and DSP integrated circuits (e.g., op-amps, ADCs, DACs, sensors) for a wide range of industries.

Application

AD8572AR is a dual, precision, low-noise op-amp suitable for:
- Instrumentation and sensor front-ends (high input impedance, low offset)
- Photodiode/current-to-voltage conversion (transimpedance amps)
- Active filters, equalizers, and integrators
- ADC/DAC driver and output buffering
- Medical and industrial instrumentation
- Audio preamplification and buffering
- Servo/control systems and precision signal conditioning

Package

AD8572AR comes in an 8‑lead plastic Small-Outline IC package (SOIC‑8).
