Description

The LT1722/LT1723/LT1724 are single/dual/quad, low 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 comparable 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 150Ω load to ±3V with ±5V supplies. On a single 5V supply the output swings from 1.5V to 3.5V with a 500Ω load connected to 2.5V. The amplifier is unity-gain stable (CLOAD ≤ 100pF).

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.
