概述

Description

The OPA348AIDR is a Texas Instruments rail-to-rail input/output operational amplifier designed for single-supply, low-power signal amplification. It provides the following:
- Rail-to-rail input and output for convenient operation from a single low-voltage supply
- Low quiescent current and low offset voltage for battery-powered/sensor apps
- Suitable common-mode range that includes ground
- Moderate bandwidth for general-purpose sensor buffering and amplification
- Available in an 8-pin package (AIDR suffix indicates a specific package/packing option, e.g., tape-and-reel)
Typical uses include buffering and amplifying low-level sensor signals, transimpedance or current-sense front-ends, and portable instrumentation. For exact electrical specs (supply range, offset, bias current, bandwidth) and packaging details, refer to the TI OPA348AIDR datasheet.

Features

Here are the typical features of TI OPA348AIDR (op-amp in the OPA348 family):
- Rail-to-rail input and output
- Single-supply operation from about 2.7 V to 5.5 V
- Unity-gain stable for buffering and buffering with gain
- Low quiescent current and low input bias current
- Low input-offset voltage and low drift
- Moderate bandwidth with fast settling for general-purpose signal conditioning
- Internal protection: input/output short-circuit tolerance and ESD protection
- Wide operating temperature range: typically –40 °C to +125 °C (industrial)
- Package: 8-pin surface-mount (MSOP/SOIC) with AIDR code (RoHS-compliant)
Note: exact electrical specs (GBW, slew rate, offset, quiescent current) vary by variant and temperature. Please consult the datasheet for precise numbers.

Package

OPA348AIDR is in an 8‑pin SOIC (D) package, RoHS‑compliant, with tape‑and‑reel packaging.

Pinout

- Pin count: 8 pins
- Function: Single-channel rail-to-rail input/output operational amplifier (op-amp) for precision amplification in single-supply applications (packages include MSOP-8/SOIC-8).

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: TI is an American multinational corporation that designs and manufactures semiconductors and integrated circuits, specializing in analog and mixed-signal devices (e.g., op-amps like OPA348) and embedded processing solutions.

Application

OPA348AIDR is a low-power, rail-to-rail input/output op-amp suited for single-supply operation. Common application areas include:
- Battery-powered portable instrumentation and sensors
- Sensor signal conditioning (amplification, offset/scale)
- Buffer/driver for ADC inputs
- Active filters and integrators in analog front-ends
- Transimpedance amplifiers for photodiodes/light sensors
- Small-signal amplification in IoT and industrial sensing

Equivalent

Are you seeking TI pin-for-pin substitutes or cross-vendor equivalents for OPA348AIDR? If pin-compatible, the closest TI parts are RRIO op-amps in the OPAx34x/OPA3x families (e.g., OPA347AIDR). For cross-vendor substitutions, please specify your supply voltage, required bandwidth/slew rate, input/output rail requirements, and package so I can tailor matches.
