Low Noise Precision Op Amps

The LT

noise, low power, high speed operational amplifiers. These

products feature lower input offset voltage, lower input

bias current and higher DC gain than devices with compa-

rable bandwidth. The 200MHz gain bandwidth ensures

high open-loop gain at video frequencies.

The low input noise voltage is achieved with reduced

supply current. The total noise is optimized for a source

resistance between 0.8k and 12k. Due to the input bias

current cancellation technique used, the resistance seen

by each input does not need to be balanced.

The output drives a 150

Ω load to ±3V with ±5V supplies.

On a single 5V supply the output swings from 1.5V to 3.5V

The LT1722/LT1723/LT1724 are manufactured on Linear

Technology’s advanced low voltage complementary

bipolar process. The LT1722 is available in the SO-8 and

5-pin SOT-23 packages. The LT1723 is available in the

SO-8 and MS8 packages. The LT1724 is available in the

14-lead SO package.
