TSH341ILT

P1-P3P4-P6P7-P9P10-P12P13-P13
March 2005 Revision 2 1/13
■ Bandwidth: 300MHz
■ Single supply operation down to 3V
■ Low input & output rail
■ Very low harmonic distortion
■ Slew rate: 400V/µs
■ Voltage Input noise: 7nV/√Hz
■ Specified for 150Ω load and 100Ω load
■ Tested on 5V power supply
■ Data min. and max. are tested during
production (Table 3)
Description
The TSH341 is a single supply operational
amplifier featuring a large bandwidth of 300MHz
at unity gain for only 9.8mA of quiescent current.
An advantage of this circuit is its low input and
output rail feature which is very close to GND in
single supply. This rail is tested and guaranteed
during production at 60mV (max.) from GND on a
150
Ω load. This allows a good output swing which
fits perfectly when driving a video signal on a 75Ω
video line. Chapter 5 gives technical support
when using the TSH341 as a driver for video DAC
output on a video line. In particular, this chapter
focuses on applying a video signal DC shift to
avoid any clamping of the synchronization tip.
The TSH341 is available in the tiny SOT23-5 and
SO8 plastic packages.

4) 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.
