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 140 MHz, and offers excellent DC precision and dynamic AC performance at a low quiescent current (IQ) of 3.7 mA per channel. The OPA810 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 70 MHz, slew rate of 200 V/µs, and low-noise voltage of 6.3 nV/√ Hz, the OPA810 is well suited 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 75 mA of linear output current, suitable for driving optoelectronics components and analog-to-digital converter (ADC) inputs or buffering digital-to-analog converter (DAC) outputs into heavy loads.
The OPA810 is rated over the extended industrial temperature range of –40°C to +125°C. The OPA2810 is a dual-channel variant of this device, available in 8-pin SOIC, SOT-23, and VSSOP packages.
