Texas Instruments OPA192 Precision Operational Amplifier, SOT-23

The Texas Instruments OPA192IDBVR is a high‑voltage precision operational amplifier designed for demanding industrial applications. It features rail‑to‑rail input and output, delivering outstanding DC precision and excellent AC performance in a compact SOT‑23 package. This robust amplifier combines a wide differential input‑voltage range that extends to the supply rail with a high output current of ±65 mA, making it capable of driving challenging loads.

A key advantage is its high capacitive‑load drive capability of up to 1 nF, coupled with a fast slew rate of 20 V/µs, which ensures clean signal integrity even in high‑speed circuits. The device incorporates EMI/RFI filtered inputs, enhancing its resilience in electrically noisy environments typical of industrial settings.

Precision Performance

Engineered for accuracy, the OPA192 offers remarkably low offset voltage (±5 µV) and an ultra‑low offset voltage drift of just ±0.2 µV/°C. This stability over temperature is critical for precision measurement. It also boasts low noise (5.5 nV/√Hz at 1 kHz), high common‑mode rejection (140 dB), and very low input bias current (±5 pA), contributing to superior signal fidelity.

Versatile Power and Applications

With a wide supply voltage range from 4.5 V to 36 V (±2.25 V to ±18 V), it offers great design flexibility. Its low quiescent current of 1 mA per amplifier makes it suitable for power‑sensitive designs. This green product is manufactured without antimony or brominated flame retardants.

Ideal for test and measurement equipment, precision signal‑processing chains, and sensing instrumentation, the OPA192 provides a reliable, high‑performance solution where accuracy, speed, and robustness are paramount.
