27V, 140MHz, single channel, high performance, RRIO FET input op amp | DBV | 5 | -40 to 125

The OPA810 is a single-channel,

field-effect transistor (FET) input, voltage-feedback operational amplifier with

bias current in the picoampere (pA) range. The OPA810 is unity-gain stable with a

small-signal, unity-gain bandwidth of 140MHz, and offers excellent dc precision and

dynamic ac performance at a low quiescent current (IQ) of 3.7mA per

channel. The OPA810 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, slew rate of 200V/µs, and low-noise voltage of 6.3nV/√Hz,

the OPA810 is designed for use in a wide range of high-fidelity data-acquisition and

signal-processing applications.

The OPA810 features rail-to-rail

inputs and outputs, and delivers 75mA of linear output current designed to drive

optoelectronic components and analog-to-digital converter (ADC) inputs or buffer

digital-to-analog converter (DAC) outputs into heavy loads.

The OPA810 is specified over the

extended industrial temperature range of –40°C to +125°C. The OPA2810 is a

dual-channel variant of the OPA810, available in 8-pin SOIC, SOT-23, and VSSOP

packages.
