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.

STANDBY POSITION
To put thedevicein standby, just applya logiclevel
on the standby MOS input. As ground is a virtual

- 1.6V typ.
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
to 2.5Vpp.
