PRODUCT DESCRIPTION

gains. This makes the AD744 ideal for use as ac preamps in

digital signal processing (DSP) front ends.

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 AD744 is available in five performance grades. The AD744J

and AD744K are rated over the commercial temperature range

of 0°C to +70°C. The AD744A and AD744B are rated over

the industrial temperature range of –40°C to +85°C. The AD744T

is rated over the military temperature range of –55°C to +125°C

and is available processed to MIL-STD-883B, Rev. C.

The single-pole response of the AD744 provides fast settling:

500 ns to 0.01%. This feature, combined with its high dc preci-

sion, 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 band-

width 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 available in an 8-lead plastic mini-DIP, 8-lead

small outline, 8-lead cerdip or TO-99 metal can.

PRODUCT HIGHLIGHTS

1. The AD744 is a high-speed BiFET op amp that offers excel-

lent performance at competitive prices. It outperforms the

OPA602/OPA606, LF356 and LF400.

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.

2. The AD744 offers exceptional dynamic response. It settles to

0.01% in 500 ns and has a 100% tested minimum slew rate

of 50 V/µs (AD744B).

3. The combination of Analog Devices’ advanced processing

technology, laser wafer drift trimming and well-matched

ionimplanted JFETs provide outstanding dc precision. Input

offset voltage, input bias current, and input offset current are

specified in the warmed-up condition; all are 100% tested.

Alternatively, external decompensation may be used to increase

the gain bandwidth of the AD744 to over 200 MHz at high

REV. C
