DESCRIPTION
The LT
noise, low power, high speed operational amplifi ers. 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 amplifi er
is unity-gain stable (C
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.
