概述

Description

OPA378AIDCKR is Texas Instruments’ precision operational amplifier in an 8-pin package. It’s designed for high-accuracy signal conditioning in instrumentation, sensor interfaces, and ADC front-ends. Key points:
- Very low input offset voltage and drift, low input bias current, and low noise
- Wide supply range with rail-to-rail input/output (suitable for single- or dual-supply designs)
- Unity-gain stable and well-suited for precision amplifiers, transimpedance, and servo loops
- Available in RoHS-compliant AIDCKR packaging (8-pin, reel/tape)
For exact specs (offset, drift, noise, bandwidth, slew rate, and supply rails) and precise packaging details, consult the TI datasheet and product page.

Features

Here are key features of the OPA378AIDCKR (TI op-amp):
- Precision, low-offset voltage with low drift
- Very low input bias current
- Low noise performance for sensor conditioning
- Rail-to-rail input and output for single-supply operation
- Unity-gain stable; suitable for closed-loop gains of 1 or higher
- Wide supply range with low quiescent current
- Industrial temperature range suitable for harsh environments
- 8-pin small-outline package (DCKR/AIDCKR) for compact PCB designs
Note: For exact electrical parameters (offset, bias current, noise, bandwidth, supply range, etc.), please consult the official datasheet.

Package

8-pin VSSOP package (VSSOP-8), RoHS-compliant and available in Tape & Reel.

Pinout

Pin count: 8 pins (8-pin package).
Function: Single-channel precision operational amplifier (op-amp) used for high-precision signal amplification (low offset, low noise).

Manufacturer

Texas Instruments (TI). TI is an American multinational semiconductor company that designs and manufactures analog and mixed-signal integrated circuits and embedded processors.

Application
