7.1 Overview

The OPA810-Q1 is a single-channel, field-effect transistor (FET)-input, unity-gain stable, voltage-feedback operational amplifier with extremely low input bias current across the common-mode input voltage range. The OPA810-Q1, characterized to operate over a wide supply range of 4.75V to 27V, has a small-signal, unity-gain bandwidth of 140MHz and offers both excellent dc precision and dynamic ac performance at low quiescent power. The OPA810-Q1 is fabricated on Texas Instruments' 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 70MHz, extremely high slew rate (200V/µs), and low noise (6.3nV/√Hz), the OPA810-Q1 is designed for a wide range of data-acquisition and signal-processing applications. The OPA810-Q1 includes input clamps to allow maximum input differential voltage of up to 7V, making this device an excellent choice 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 3.7mA per channel.

The OPA810-Q1 can source and sink large amounts of current without degradation in linearity performance. The wide bandwidth of the OPA810-Q1 implies that the device has low output impedance across a wide frequency range, thereby allowing the amplifier to drive capacitive loads up to 10pF without requiring output isolation. This device is designed for a wide range of data-acquisition, test-and-measurement, front-end buffer, impedance-measurement, power-analyzer, wideband photodiode transimpedance, and signal-processing applications.
