excellent speed consumption ratio with 4.5 mA
per amplifier for a 150 MHz bandwidth.
High slew rate and low noise also make it suitable
for high-quality audio applications.
The TSH94 offers two separate complementary

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
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

4.1 Printed circuit layout recommendations
As for any high frequency device, a few rules must be observed when designing the PCB to
get the best performance from this high-speed op-amp.
Some recommendations are listed below, from the most important to the least important.
●By-pass each power supply lead to ground with a 10 μF capacitor and a 10 nF ceramic
capacitor 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.
●Make sure all leads are wide and as short as possible, especially for op-amp inputs.
This is to decrease parasitic capacitance and inductance.
●Use small resistor values to decrease the time constant with parasitic capacitance.
●Choose component sizes as small as possible (SMD).
●On the output, keep the capacitor load as low as possible to avoid oscillation which
would degrade the circuit stability. You can also add a serial resistor in order to
minimize the effect of the capacitor load.
