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.

PRINTED CIRCUIT LAYOUT
As for any high frequency device, a few rules must
be observed when designing the PCB to get the
best performances from this high speed op amp.
From the most to the least important points :
❑ Each power supply lead has to be
by-passed to ground with a 10nF ceramic
capacitor very close to the device and
10µF capacitor.
❑ To provide low inductance and low resist-
ance common return, us e a ground plane
or common point return for power and signal.
❑ All leads must be wide and as short as pos-
sible especially for op amp inputs. This is in
order to decrease parasitic capacitance
and inductance.
❑ Use small resistor values to decrease time
constant with parasitic capacitance.
❑ Choose component sizes as s mall as pos -
sible (SMD).
❑ On output, decrease capacitor load so as
to avoid circuit stability being degraded
which may cause oscillation. You can also
add a serial resistor in order to minimise its
influence.
