Description
The TSH350 is a current feedback operational
amplifier using a very high-speed complementary
technology to provide a bandwidth up to 410MHz
while drawing only 4.1mA of quiescent current.
With a slew rate of 940V/µs and an output stage
optimized for driving a standard 100Ω load, this
circuit is highly suitable for applications where
speed and power-saving are the main
requirements.
The TSH350 is a single operator available in the
tiny SOT23-5 and SO-8 plastic packages, saving
board space as well as providing excellent
thermal and dynamic performance.
