概述

Description

OPA4172IDR is a dual operational amplifier from Texas Instruments. It’s part of the OPA417x family and is packaged in an 8-pin package (IDR denotes a RoHS-compliant SOIC with tape-and-reel packaging). The device is designed for precision analog signal conditioning, offering low input offset and low input bias current with good noise performance. It’s suitable for sensor interfaces, instrumentation, active filters, buffering, and general-purpose amplification. The OPA4172 supports single- or dual-supply operation and provides stable, high-performance amplification for small signals in various configurations (inverting/non-inverting, integrators, etc.). For exact electrical specifications (offset, bias current, noise, bandwidth, slew rate, and supply range), refer to the TI datasheet and product page.

Features

Here are the typical features of the OPA4172IDR:
- Dual, precision op-amp with rail-to-rail input and output (RRIO)
- Very low input offset voltage and low input bias current
- Low voltage noise density for clean amplification
- High slew rate and wide bandwidth for fast signals
- Unity-gain stable; suitable for buffering and various gain configurations
- Wide supply range for single-supply or dual-supply operation
- Good temperature stability and low offset drift
- Robust output drive with good overload/short-circuit recovery
- 8-pin IDR package (industry-standard small-outline) with RoHS compliance
Note: For exact numerical specs (offset, bias current, bandwidth, slew rate, supply limits), please refer to the TI datasheet.

Package

8-pin MSOP (MSOP-8) package.

Pinout

- Pin count: 8 pins.
- Function: Dual operational amplifier (two op-amps, A and B) in one package. Typical pinout (SOIC/MSOP): Pin 1 = Output A, Pin 2 = Inverting input A, Pin 3 = Non-inverting input A, Pin 4 = V−, Pin 5 = Non-inverting input B, Pin 6 = Inverting input B, Pin 7 = Output B, Pin 8 = V+.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- About the company: TI is an American multinational technology company that designs and manufactures semiconductors and integrated circuits for electronics and various industries.

Application

OPA4172IDR is a dual, precision, low-noise op-amp. Typical applications:
- Sensor signal conditioning (thermocouples, RTDs, strain gauges)
- Transimpedance amplifiers for photodiodes/detectors
- DAC output buffers and ADC front-ends
- Instrumentation front-ends and active filters
- Audio preamplifiers and line drivers
- Servo/control systems (low offset/drift)

Equivalent

OPA4172IDR is TI’s dual, rail-to-rail input/output precision op-amp in an 8-pin package. Close equivalents (depending on your specs) include:
- TI: OPA2372, OPA2376 (dual, precision RRIO)
- Analog Devices: ADA4528-2 (dual, zero-drift, RRIO), AD8628 (dual RRIO)
- Linear Technology/Analog Devices: LTC6078 (dual, low-noise)
Note: exact cross-reference depends on GBWP, offset, noise, supply, and packaging—use TI’s cross-reference tool to match specs.
