The LT
®
1722/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 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 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 (C
LOAD
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.
