Description
The TSH94 is a quad low power high frequency
op-amp, designed for high quality video signal
processing. The device offers an excellent speed
consumption ratio with 4.5mA per amplifier for
150MHz bandwidth.
High slew rate and low noise also make it suitable
for high quality audio applications.
The TSH94 offers 2 separate complementary
STANDBY functions:
■
■
STANDBY 1 acting on the n° 2 operator
STANDBY 2 acting on the n° 3 operator
These functions reduce the consumption of the
corresponding operator and put the output in a
high impedance state.

1. All voltage values, except differential voltage are with respect to network ground terminal
2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal
3. The magnitude of input and output voltages must never exceed V
CC+
+0.3V
4. Charged device model: all pins and the package are charged together to the specified voltage and then
discharged directly to the ground through only one pin. This is done for all pins.
5. Human body model: A 100pF capacitor is charged to the specified voltage, then discharged through a
1.5kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations
while the other pins are floating.
6. Machine model: A 200pF capacitor is charged to the specified voltage, then discharged directly between
two pins of the device with no external series resistor (internal resistor < 5Ω). This is done for all couples of
connected pin combinations while the other pins are floating
