Additional Details

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.

Tools & Simulations

LTspice

LTspice® is a powerful, fast and free simulation software, schematic capture and waveform viewer with enhancements and models for improving the simulation of analog circuits.

Analog Filter Wizard

Use the Analog Filter Wizard to design low-pass, high-pass, or band-pass filters with actual op amps in minutes. As you progress through the design process, you can observe the characteristics of your filter design from ideal specifications to real world circuit behavior. Quickly evaluate the tradeoffs in op amp specifications - including gain-bandwidth, noise, and supply current – to determine the best filter design for your requirements.

Open Tool

Analog Photodiode Wizard

Use Photodiode Wizard to design a transimpedance amplifier circuit to interface with a photodiode. Select a photodiode from the library included in the tool, or enter custom photodiode specifications. Quickly observe tradeoffs between Bandwidth, Peaking (Q), and ENOB/SNR. Modify circuit parameters, and immediately see results in plots for pulse response, frequency response, and noise gain.

Open Tool

VRMS/dBm/dBu/dBV calculators

A utility to convert between standard units of power measurement and signal strength.

Open Tool

Power Dissipation vs Die Temp

This tool estimates die temperature and power dissipation based on the supply voltages, ambient temperature, load characteristics, and package thermal data.
