概要

Description

OPA627BU is a Texas Instruments Burr-Brown high-precision operational amplifier. It’s an 8‑pin device designed for low noise, very low offset and drift, low input bias current, and fast response, with a substantial output drive and high gain‑bandwidth. The BU suffix typically indicates a standard 8‑pin package (DIP/SOIC variants) used in through‑hole and surface‑mount assemblies.
Common applications include instrumentation front ends, precision active filters, transimpedance and photodiode amplifiers, servo/control loops, and high‑quality audio preamps. It excels where accuracy, stability, and speed matter, though it is not rail‑to‑rail and requires suitable supply rails within the datasheet’s range.
For exact specs (GBW, slew rate, input offset/noise, supply range, and stability in closed‑loop configurations), consult the TI OPA627 datasheet and the specific BU package variant in your region.

Features

OPA627BU features (highlights):
- Precision BiFET input op-amp: ultra-low offset voltage and drift with very low input bias current
- Low noise and high speed: fast transient response and good stability for precision signal conditioning
- Unity-gain stable: suitable for buffering and a wide range of closed-loop gains
- Wide supply range with good PSRR/CMRR: compatible with standard ± and single-supply rails
- Robust output drive for moderate loads and fast settling
- Industrial temperature range: -55°C to +125°C
- Packaging: 8-pin plastic package (BU suffix) for easy PCB integration
Typical applications: precision instrumentation, data acquisition front-ends, active filters, and high-accuracy signal amplification.

Package

OPA627BU comes in an 8-pin small-outline package (SOIC-8), i.e., a plastic SOIC package.

Pinout

Pin count: 8 pins.
Function: Single, high-precision, low-noise operational amplifier (op-amp). Typical pinout (SOIC/DIP 8‑pin): 1 and 8 = offset null; 2 = inverting input; 3 = non-inverting input; 4 = V−; 5 = no connect; 6 = output; 7 = V+.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: An American multinational technology company that designs and manufactures semiconductors and integrated circuits (notably analog/mixed-signal devices and embedded processors).
