The OPA2810 is a dual-channel, FET-input, voltage-feedback operational amplifier with
low input bias current. The OPA2810 is unity-gain stable with a small-signal unity-gain bandwidth
of 105 MHz, and offers excellent DC precision and dynamic AC performance at a low quiescent current
(IQ) of 3.6 mA per channel (typical). The OPA2810 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 70 MHz, slew-rate of 192 V/µs, and voltage low-noise of 6
nV/√Hz, the OPA2810 is well suited for use in a wide range of high fidelity
data acquisition and signal processing applications.
The OPA2810 is characterized to operate over a wide supply range of 4.75 V to 27 V, and
features rail-to-rail inputs and outputs. The OPA2810 amplifier delivers 75 mA of linear output
current, suitable for driving optoelectronics components and analog-to-digital converter (ADC)
inputs or buffering DAC outputs into heavy loads.
The OPA2810 is available in an 8-pin, SOT23-8 and VSSOP-8 package and is rated to work
over the extended industrial temperature range of –40°C to +125°C.
