The AD744 is a fast-settling, precision, FET input, monolithic gains. This makes the AD744 ideal for use as ac preamps in operational amplifier. It offers the excellent dc characteristics digital signal processing (DSP) front ends. of the AD711 BiFET family with enhanced settling, slew rate, The AD744 is available in five performance grades. The AD744J and bandwidth. The AD744 also offers the option of using and AD744K are rated over the commercial temperature range custom compensation to achieve exceptional capacitive load of 0°C to +70°C. The AD744A and AD744B are rated over drive capability. the industrial temperature range of –40°C to +85°C. The AD744T The single-pole response of the AD744 provides fast settling: is rated over the military temperature range of –55°C to +125°C 500 ns to 0.01%. This feature, combined with its high dc preci- and is available processed to MIL-STD-883B, Rev. C. sion, makes it suitable for use as a buffer amplifier for 12-bit, The AD744 is available in an 8-lead plastic mini-DIP, 8-lead 14-bit or 16-bit DACs and ADCs. Furthermore, the AD744’s low small outline, 8-lead cerdip or TO-99 metal can. total harmonic distortion (THD) level of 0.0003% and gain band- width product of 13 MHz make it an ideal amplifier for demanding
