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

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.

4.1 Printed circuit layout recommendations

As with any high-frequency device, a few rules must be observed when designing the PCB so as to maximize performance.
From the most to the least important points:
● Each power supply lead must be bypassed to ground with a 10 nF ceramic capacitor
and a 10 μF capacitor placed very close to the device.
● To provide low inductance and low resistance common return, use a ground plane or
common point return for power and signal.
● All leads must be wide and as short as possible, especially for the inputs, in order to
decrease parasitic capacitance and inductance.
● Use small resistor values to decrease the time constant with parasitic capacitance.
● Choose the smallest-possible component sizes (SMD).
● Decrease the capacitor load at the output to avoid degrading the circuit’s stability and
cause oscillation. You can also add a serial resistor to minimize its influence.
