DESCRIPTION:
The TSH151is a widebandmonolithic operational
amplifier,internallycompensatedforunity-gainstability.
The TSH151features extremely high input impedance (typically greater than 10
12
Ω) allowing direct
interfacingwith high impedance sources.
Low distortion, wide bandwidth and high linearity
make this amplifiersuitableforRF and video applications. Short circuit protection is provided by an
internal current-limiting circuit.
The TSH151 has internal electrostatic discharge
(ESD)protection circuits andfulfillsMILSTD883CClass2.

EVALUATION CIRCUIT
As for any high frequencydevice, a fewrules must
be observedwhendesigningthe PCBto getthe best
performancesfrom your this speed op amp.
From the most to the least important points :
• Each power supply lead has to be bypassed
to ground with a 10nF ceramic capacitor very
close to the deviceand a 10µF tantalum ca-
pacitor.
• To providelow inductanceand low resistance
common return, use a ground plane or common point return for power and signal.
• All leads must be wideand as short as possi-
ble especially for op amp inputs. This is in
order to decrease parasitic capacitance and
inductance.
• Use small resistor values to decrease time
constantwith parasitic capacitance.
• Choosecomponentsizesassmallaspossible
(SMD).
• On output, decrease capacitor load so as to
avoid circuit stability being degraded which
may cause oscillation. One can also add a
serial resistor in order to minimise its influence.
• One can addin parallelwithfeedbackresistor
a few pF ceramic capacitor C
F
adjusted to
optimizethe settlingtime.
