The OPAx863 series from Texas Instruments includes the OPA863, OPA2863, and OPA4863, which are low-power, rail-to-rail input/output, voltage-feedback operational amplifiers designed for high-performance applications. These amplifiers feature a unity-gain bandwidth of 110 MHz, a gain-bandwidth product of 50 MHz, and a low quiescent current of 700 µA per channel. The devices operate across a wide supply voltage range of 2.7 V to 12.6 V, making them suitable for both portable and battery-powered systems. With a slew rate of 105 V/µs, 5.9 nV/√Hz input voltage noise, and exceptional harmonic distortion performance (-129 dBc HD2, -138 dBc HD3 at 20 kHz for 2 Vpp output), the OPAx863 is adept for driving SAR and ΔΣ ADCs, acting as ADC reference buffers, low-side current sensing, photodiode TIA interfaces, and other high-precision tasks. Additional features include overload power limiting, output short-circuit protection, and a power-down mode with minimal quiescent current, making the OPAx863 series a versatile and robust choice for applications requiring low power and high-precision analog performance. The series includes single, dual, and quad-channel configurations available in various surface-mount packages to fit different design requirements.
