Description
The TSH95 is a low-power, high-frequency quad
operational amplifier designated for high-quality
video processing. The device offers an excellent
speed consumption ratio with 4.5 mA per
amplifier for a 150 MHz bandwidth.
A high slew rate and low noise also make it
suitable for high-quality audio applications.
The TSH95 offers two separate complementary
STANDBY pins: STANDBY 1 acting on operators
1 and 2, and STANDBY 2 acting on operators 3
and 4.
These pins reduce the consumption of the
corresponding operators and put the output in a
high impedance state.

1. All voltages 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
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 100 pF capacitor is charged to the specified voltage, then discharged through a
1.5 kΩ 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 200 pF capacitor is charged to the specified voltage, then discharged directly between
two pins of the device with no external series resistor (internal resistor < 5 Ω). This is done for all couples of
connected pin combinations while the other pins are floating

To put the device in standby, a logic level must be applied on the standby MOS input. Since

In standby mode, the output goes into high impedance in 200 ns. Note that all maximum
ratings must still be followed in this mode. This mode leads to a swing limitation while using
the device in a signal multiplexing configuration with followers; the differential input voltage
must not exceed ±5 V, limiting the input swing to 2.5 Vpp.
