Description
The TSH330 is a current feedback operational
amplifier using a very high-speed complementary
technology to provide a large bandwidth of
1.1GHz in gain of 2 while drawing only 16.6mA of
quiescent current. In addition, the TSH330 offers
0.1dB gain flatness up to 160MHz with a gain of 2.
With a slew rate of 1800V/µs and an output stage
optimized for driving a standard 100
device is highly suitable for applications where
speed
requirements.
The TSH330 is a single operator available in the
SO8 plastic package, saving board space as well
as providing excellent thermal and dynamic
performances.
