Overview

Description

OPA1641AIDR is Texas Instruments’ precision, low-noise operational amplifier. It’s part of the OPA1641 family and is geared toward audio, instrumentation, and sensor-conditioning front-ends. Key points:
- Very low input-referred noise and low distortion
- Low input bias current and wide supply range with good power-supply rejection
- High slew rate and bandwidth, suitable for signal conditioning and buffering
- Unity-gain stable and capable of driving moderate loads directly
The AIDR suffix denotes the specific TI packaging/format (an 8-pin device in TI’s reel packaging for automated assembly). For exact electrical specs, thermal data, and packaging details, see the OPA1641AIDR datasheet on TI’s website.

Features

OPA1641AIDR features (concise):
- Dual, high-precision, low-noise operational amplifiers
- Very low input-referred noise and low input bias current
- High slew rate and wide bandwidth for fast, accurate signals
- Low distortion with high linearity (good THD+N)
- High open-loop gain with excellent DC accuracy
- Unity-gain stable; suitable for buffers and amplification stages
- Wide supply voltage range; supports single or dual-supply operation
- Good power-supply rejection (PSRR) and common-mode rejection (CMRR)
- Robust drive capability for moderate to heavy loads
- 8-pin VSSOP (AIDR)RoHS package
Typical uses: audio preamps and front-ends, DAC/ADC front-ends, active filters, instrumentation and other precision analog applications.
Note: check datasheet for exact electrical numbers and safe operating conditions.

Package

OPA1641AIDR comes in an 8-pin SOIC package (D-package), RoHS compliant.

Pinout

- Pin count: 8 pins (8-pin package, e.g., SOIC-8)
- Function: Dual operational amplifier (two op-amps in one package; high-precision, low-noise).

Manufacturer

Manufacturer: Texas Instruments (TI).
Type of company: TI is an American multinational semiconductor company that designs and manufactures analog and embedded processing ICs.

Application

OPA1641AIDR is a high-precision, low-noise dual op-amp from TI. Typical applications include audio front-ends (mic/line preamps, DAC I/V stages, headphone drivers), active filters and EQs, instrumentation and sensor signal conditioning, precision ADC/DAC front-ends, servo loops, and general high-fidelity analog signal processing (medical, industrial, portable equipment).

Equivalent

OPA1641AIDR is TI’s high‑fidelity audio op‑amp (MSOP-8). Closest TI substitutes: OPA1640AIDR and OPA1612AIDR (similar performance in the same family). Cross‑vendor options with comparable specs: Analog Devices ADA4896‑1 and ADA4627‑1. Always verify pinout, supply, bandwidth, and noise specs for your design.
