amplifier for high-speed applications demanding low noise and

high dc precision. Furthermore, the AD745 does not exhibit an

output phase reversal.

The AD745 also has excellent dc performance with 250 pA

maximum input bias current and 0.5 mV maximum offset voltage.

Low Noise Preamplifiers

High Performance Audio

The internal compensation of the AD745 is optimized for higher

gains, providing a much higher bandwidth and a faster slew

rate. This makes the AD745 especially useful as a preamplifier

where low level signals require an amplifier that provides both

high amplification and wide bandwidth at these higher gains.

The AD745 is available in two performance grades. The AD745J

and AD745K are rated over the commercial temperature range

of 0°C to 70°C, and are available in the 16-lead SOIC package.

PRODUCT DESCRIPTION

The AD745 is an ultralow noise, high-speed, FET input opera-

tional amplifier. It offers both the ultralow voltage noise and

high speed generally associated with bipolar input op amps and

the very low input currents of FET input devices. Its 20 MHz

bandwidth and 12.5 V/µs slew rate makes the AD745 an ideal
