SBOS789C August 2017 – February 2020 OPA2810
The OPA2810 is a dual-channel, FET-input, unity-gain stable voltage-feedback operational amplifier with extremely low input bias current across its common-mode input voltage range. The OPA2810, characterized to operate over a wide supply range of 4.75 V to 27 V, has a small-signal unity-gain bandwidth of 105 MHz and offers both excellent DC precision and dynamic AC performance at low quiescent power. The OPA2810 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 70MHz, extremely high slew-rate (192 V/µs), and low-noise (6 nV/√Hz) the OPA2810 is ideal in a wide range of data acquisition and signal processing applications. The OPA2810 includes input clamps to allow maximum input differential voltage of up to 7 V, making it suitable for use with multiplexers and processing of signals with fast transients. It achieves these benchmark levels of performance while consuming a typical quiescent current (IQ) of 3.6 mA /channel.
The OPA2810 can source and sink large amounts of current without degradation in its linearity performance. The wide-bandwidth of the OPA2810 implies that the device has low output-impedance across a wide frequency range, thereby allowing the amplifier to drive capacitive loads up to 35 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.
