DESCRIPTION
The TSH95 is a quad low power high frequency op-amp, designated for high quality video pro-cessing. 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 TSH95 offers 2 separate complementary STANDBY pins :
u STANDBY 1 acting on both n° 1 & 2operators
nvnuu STANDBY 2 acting on both n° 3 & 4operators
They reduce the consumption of the correspond-ing operatorS and put the output in a high imped-ance state.ORDER CODE

APPLICATIONS
SIGNAL MULTIPLEXING
STANDBY MODE
To put the device in standby, just apply a logic level on the standby MOS input. As ground is a vir-tual level for the device, threshold voltage has been refered to V CC + at V CC + - 1.6V typ.
In standby mode, the output goes in high imped-ance 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, differen-tial input voltage must not exceed ±5V limiting in-put swing to 2.5Vpp.SAMPLE AND HOLD

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 :
u Each power supply lead has to be
by-passed to ground with a 10nF ceramic capacitor very close to the device and 10µF capacitor.
u To provide low inductance and low resist-ance common return, use a ground plane or common point return for power and sig-nal.
u 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.
u Use small resistor values to decrease time
constant with parasitic capacitance.
u Choose component sizes as small as pos-sible (SMD).
u 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.
