DESCRIPTION
The TSH94 is a quad low power high frequency
op-amp, designated for high quality video signal
processing. The device offers an excellent speed
consumption ratio with 4.5mA/amp. for 150MHz
bandwidth.
High slew rate and low noise make it also suitable
for high quality audio applications.
The TSH94 offers 2 separate complementary
STANDBY pins :
• STANDBY1 acting on the n°2 operator
• STANDBY2 acting on the n°3 operator
Theyreducetheconsumptionofthecorresponding
operator and put the output in a high impedance
state.

In standby mode, the output goes in high impedance in 200ns. Be aware that all maximum rating
muststillbe followedin thismode. It leadsto swing
limitationwhile usingthe deviceinsignal multiplexing configuration with followers, differential input
voltage must not exceed ±5V limiting input swing

VIDEO LINE TRANSCEIVERWITH REMOTE CONTROL
As for anyhigh frequencydevice, a few rules must
be observed when designing the PCB to get the
best performancesfrom this highspeed op amp.
From the most to the least important points :
•
Each power supply leadhas to beby-passedto
groundwith a 10nFceramiccapacitor very
closeto the deviceand 10µF capacitor.
•
To providelow inductanceand low resistance
commonreturn, use a groundplane or common point return for power and signal.
•
All leads mustbe wideand as short as possible
especially for op amp inputs.This is in orderto
decreaseparasitic capacitanceand inductance.
•
Use smallresistor values to decreasetime constant with parasitic capacitance.
•
Choose componentsizes as small as possible
(SMD).
•
On output, decreasecapacitor load so as to
avoid circuit stabilitybeing degraded which
may cause oscillation.Youcan also add a serial resistor in order to minimise its influence.
