8.1 Overview

The OPA810 is a single-channel, field-effect transistor (FET)-input, unity-gain stable, voltage-feedback operational amplifier with extremely low input bias current across its common-mode input voltage range. The OPA810, characterized to operate over a wide supply range of 4.75 V to 27 V, has a small-signal, unity-gain bandwidth of 140 MHz and offers both excellent DC precision and dynamic AC performance at low quiescent power. The OPA810 is fabricated on Texas Instrument's proprietary, high-speed SiGe BiCMOS process and achieves significant performance improvements over comparable FET-input amplifiers at similar levels of quiescent power. With a gain-bandwidth product (GBWP) of 70 MHz, extremely high slew rate (200 V/µs), and low noise (6.3 nV/√ Hz), the OPA810 is ideal in a wide range of data acquisition and signal processing applications. The OPA810 includes input clamps to allow maximum input differential voltage of up to 7 V, making the device suitable for use with multiplexers and for processing signals with fast transients. The device achieves these benchmark levels of performance while consuming a typical quiescent current (IQ) of 3.7 mA per channel.

The OPA810 can source and sink large amounts of current without degradation in its linearity performance. The wide bandwidth of the OPA810 implies that the device has low output impedance across a wide frequency range, thereby allowing the amplifier to drive capacitive loads up to 10 pF without requiring output isolation. This device is suitable for a wide range of data acquisition, test and measurement front-end buffer, impedance measurement, power analyzer, wideband photodiode transimpedance, and signal processing applications.
