Revision 1
1/7
Gain flatness of 110MHz
Bandwidth: 320MHz
Single supply operation down to 3V
Tested on 5V power supply
Negative input & output rail
Very low harmonic distortion
Slew rate: 400V/s typ., 290V/s min.
Input noise: 3nV/Hz
Specified for 150 load
Description
The TSH341 is a video operational amplifier of
320MHz bandwidth for only 9.3mA of quiescent
current. This allows to achieve a gain flatness of
110MHz. Its structure features a very high slew
rate of 290V/
s minimum guaranteed by test. With
a very good THD associated to these
characteristics the TSH341 is particularly
intended in the high quality video systems.
The TSH341 is available in tiny SOT23-5 and SO8
plastic packages for size saving consideration.

An output current limitation protects the circuit from transient currents. Short-circuits can cause excessive heating.
Destructive dissipation can result from short circuit on amplifiers.
