Texas Instruments OPA2810 Rail-to-Rail I/O FET Op Amps

Texas Instruments OPA2810 High-Performance Rail-to-Rail Input/Output Operational Amplifiers offer a dual-channel, voltage-feedback amp including a low input bias current. The device is unity-gain stable with a small-signal unity-gain bandwidth of 105MHz. The OPA2810 ideal DC precision and dynamic AC performance at a low quiescent current (IQ) of 3.6mA per channel (typical). Using TI's proprietary, high-speed SiGe BiCMOS process, the device achieves significant performance gains than previous versions. The OPA2810 is an excellent choice for use in a wide range of high-fidelity data acquisition and signal processing applications. Features include a gain-bandwidth product (GBWP) of 70MHz, a slew rate of 192V/µs, and a voltage low-noise of 6nV/√Hz. A wide supply range of 4.75V to 27V is available on the device with rail-to-rail inputs and outputs. The OPA2810 delivers 75mA of linear output current, making it capable of driving optoelectronics components and analog-to-digital converter (ADC) inputs or buffering DAC outputs into heavy loads.
