The Texas Instruments OPA810 is a single-channel, FET-input, voltage-feedback operational amplifier with bias current in the pA range. The device is unity-gain stable with a small-signal, unity-gain bandwidth of 140MHz, and provides excellent DC precision and dynamic AC performance at a low quiescent current of 3.7mA per channel. The device is fabricated on the company’s proprietary, high-speed SiGe BiCMOS process and delivers significant performance enhancements over comparable FET-input amplifiers at comparable levels of quiescent power. With a gain-bandwidth product of 70MHz, slew rate of 200V/µs, and low-noise voltage of 6.3nV/√Hz, the device is ideal for usage in an extensive range of high-fidelity data acquisition and signal processing applications.
The device features rail-to-rail inputs and outputs and delivers 75mA of linear output current, suitable for driving optoelectronics components and ADC inputs or buffering DAC outputs into heavy loads.
The op-amp is rated over the extended industrial temperature range of –40C to +125C. The OPA2810 is a dual-channel variant of this device, available in eight-pin SOIC, SOT23, and VSSOP packages.
