DESCRIPTION
The TSH95 is a quad low power high frequency
op-amp, designed for high quality video processing.Thedeviceoffersan excellent speedconsumption ratio with 4.5mA per operator for 150MHz
bandwidth.
High slew rate and low noise make it suitable for
high quality audio applications.
The TSH95 offers 2 separate complementary
STANDBY pins :
• STANDBY1 acting on both n° 1 & 2 operators
• STANDBY2 acting on both n° 3 & 4 operators
Theyreducetheconsumptionofthecorresponding
operatorsandput their output ina high impedance
state.

PRINTEDCIRCUIT LAYOUT
TSH95
As for any high frequency device,a few rules must
be observed when designing the PCB to get the
best performancesfrom this high speed op amp.
From the most to the least important points :
•
Each power supply lead has to be by-passedto
ground with a 10nF ceramic capacitor very
close to the device and 10µF capacitor.
•
To provide low inductance and low resistance
common return, use a ground plane or common
point return for power and signal.
INPUT OFFSET VOLTAGE DRIFT VERSUS
TEMPERATURE
•
All leads must be wide and as short as possible
especially for op amp inputs. This is in order to
decreaseparasiticcapacitance and inductance.
•
Use small resistor values to decreasetime constant with parasitic capacitance.
•
Choose component sizes as small as possible
(SMD).
•
On output, decrease capacitor load so as to
avoid circuit stability being degraded which may
cause oscillation. You can also add a serial resistorin order to minimise its influence.
