Présentation

Description

OPA2991SIRUGR is a Texas Instruments single-channel precision operational amplifier. It offers rail-to-rail input/output, very low input offset voltage, low input bias current, and low noise. It supports single- and dual-supply operation, is unity-gain stable, and is suitable for sensor conditioning, instrumentation front-ends, transimpedance amplifiers, active filters, and audio preamps. The SIRUGR suffix indicates RoHS-compliant, tape-and-reel packaging in an 8-pin surface-mount package (typical for VSSOP-8/SOIC-8).

Equivalent

Direct cross-reference for OPA2991SIRUGR isn’t exact; closest functional equivalents are:
- Analog Devices: ADA4528-1 / ADA4528-2 (zero-drift, RRIO op-amps)
- Texas Instruments: OPA333, OPA2333 (zero-drift, RRIO)
- Texas Instruments: OPA2277 (low-noise, precision)
Consult a cross-reference tool for exact pin compatibility and packaging, since dual devices may differ in footprint.

Pinout

The OPA2991SIRUGR is an 8-pin dual operational amplifier. Pin functions (typical dual-op-amp 8-pin pinout):
1. OUT A — Output of amplifier A
2. −IN A — Inverting input of amplifier A
3. +IN A — Noninverting input of amplifier A
4. V− (VSS) — Negative supply/ground
5. +IN B — Noninverting input of amplifier B
6. −IN B — Inverting input of amplifier B
7. OUT B — Output of amplifier B
8. V+ — Positive supply
(OPA2991 is a dual, precision, rail‑to‑rail output op amp; confirm exact pin names in the device datasheet for your package variant.)

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: American multinational semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing integrated circuits. Headquartered in Dallas, Texas.

Application

OPA2991SIRUGR is a precision, low-noise operational amplifier. Key application areas include:
- Sensor signal conditioning (thermistors/RTDs/strains gauges)
- Transimpedance amplifiers for photodiodes and optical detectors
- ADC front-end buffering and precision gain stages
- High-impedance voltage followers and active filters
- Medical, industrial, and consumer instrumentation needing low offset/ drift
- Audio/preamplifier stages in compact systems
These uses leverage its low-noise, high-precision amplification for accurate signal conditioning and front-end performance.

Package

Do you mean the physical IC package (e.g., SOIC, VSSOP) or the shipping format (tape‑and‑reel/tube)? I can look up the OPA2991SIRUGR datasheet and give the exact package and tape‑and‑reel details—shall I proceed?
