AD744KNZ

AD744KNZ is a fast-settling, precision, FET input, monolithic operational amplifier. It offers the excellent DC characteristics of the AD711 BiFET family with enhanced settling, slew rate, and bandwidth. It also offers the option of using custom compensation to achieve exceptional capacitive load drive capability. It is internally compensated for stable operation as a unity gain inverter or as a noninverting amplifier with a gain of two or greater. External compensation may be applied to the device for stable operation as a unity gain follower. External compensation also allows the device to drive 1000pF capacitive loads, slewing at 10V/µs with full stability. It is used in applications such as output buffers for 12bit, 14-bit, and 16-bit DACs, ADC buffers, cable drivers, wideband, preamplifiers, and active filters.
