The AD744 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. The AD744 also offers the option of using custom compensation to achieve exceptional capacitive load drive capability. The single-pole response of the AD744 provides fast settling: 500 ns to 0.01%. This feature, combined with its high dc precision, makes it suitable for use as a buffer amplifier for 12-bit, 14-bit or 16-bit DACs and ADCs. Furthermore, the AD744's low total harmonic distortion (THD) level of 0.0003% and gain bandwidth product of 13 MHz make it an ideal amplifier for demanding audio applications. It is also an excellent choice for use in active filters in 12-bit, 14-bit and 16-bit data acquisition systems. The AD744 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 AD744 for stable operation as a unity gain follower. External compensation also allows the AD744 to drive 1000 pF capacitive loads, slewing at 10 V/µs with full stability. Alternatively, external decompensation may be used to increase the gain bandwidth of the AD744 to over 200 MHz at high gains. This makes the AD744 ideal for use as ac preamps in digital signal processing (DSP) front ends. The AD744 is available in seven performance grades. The AD744J and AD744K are rated over the commercial temperature range of 0°C to +70°C. The AD744A, AD744B and AD744C are rated over the industrial temperature range of -40°C to +85°C. The AD744S and AD744T are rated over the military temperature range of -55°C to +125°C and are available processed to MIL-STD-883B, Rev. C. Extended reliability PLUS screening is available, specified over the commercial and industrial temperature ranges. PLUS screening includes a 168-hour burn-in, as well as other environmental and physical tests. The AD744 is available in an 8-pin plastic mini-DIP, 8-pin small outline, 8-pin cerdip or TO-99 metal can.
