DESCRIPTION
The TSH94 is a quad low power hi gh frequency
op-amp, designated for high qua lity vi deo signal
processing. The device offers an excellent speed
consumption ratio with 4.5mA per amplifier 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 :
❑ STANDBY 1 acting on the n° 2 operator
❑ STANDBY 2 acting on the n° 3 operator
They reduce the consumption of the corresponding operator and put the output in a high impedance state.

APPLICATIONS
SIGNAL MULTIPLEXING
standby
To put the device in standby, just apply a logic
level on the standby MOS input. As ground is a virtual level for the device, threshold voltage has
been refered to V
CC
+
at V
+
- 1.6V typ.
CC
In standby m ode, the output goes in hi gh impedance in 200ns. Be aware that all maximum rating
must still be followed in this mode. It leads to
swing limitation while using the device in signal
multiplexing configuration with followers, differential input voltage mu st not exceed ±5V limit ing input swing to 2.5Vpp.
