The OPA810-Q1 is a single-channel, field-effect transistor (FET) input, voltage-feedback operational amplifier (op amp) with bias current in the picoampere (pA) range. The OPA810-Q1 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-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, slew rate of 200V/µs, and low-noise voltage of 6.3nV/√Hz, the OPA810-Q1 is designed for use in a wide range of high-fidelity data-acquisition and signal-processing applications.

The OPA810-Q1 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-Q1 is specified over the extended industrial temperature range of –40°C to +125°C. The OPA810-Q1 is available in SOT-23 package.
