The OPA684IDR is a low-power, wideband current-feedback operational amplifier designed for high-performance applications. It features an internally closed-loop input buffer stage that enhances performance compared to traditional low-power current-feedback amplifiers. This architecture allows for a very low and linearized impedance path at the inverting input, improving bandwidth and harmonic distortion at higher gains. The amplifier supports a bandwidth greater than 120 MHz for gains above +10 and exhibits low distortion levels of less than -78 dBc at 5 MHz. It can deliver a high output current of 120 mA while operating on a single supply voltage ranging from +5V to +12V or dual supplies of ±2.5V to ±6.0V. The OPA684IDR consumes a low supply current of 1.7 mA and features a shutdown mode that reduces current to 100 µA. Applications for the OPA684IDR include low-power broadcast video drivers, equalizing filters, high-gain post amplifiers for SAW filters, multichannel summing amplifiers, and ADC input drivers. Its robust design and minimal output headroom requirements make it suitable for demanding applications, particularly in professional cameras and broadcast video systems.
