DESCRIPTION:
The TSH151 is a wideband monolithic operational
amplifier, internally compensated for unity-gain sta-
bility.
The TSH151 features extremely high input imped-
ance (typically greater than 10
12
) allowing direct
interfacing with high impedance sources.
Low distortion, wide bandwidth and high linearity
make this amplifier suitable for RF and video appli-
cations. Short circuit protection is provided by an
internal current-limiting circuit.
The TSH151 has internal electrostatic discharge
(ESD) protection circuits and fulfills MILSTD883C-
Class2.

EVALUATION CIRCUIT
As for any high frequency device, a few rules must
be observed when designing the PCB to get the best
performances from 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 device and a 10
F tantalum ca-
pacitor.
To provide low inductance and low resistance
common return, use a ground plane or com-
mon point return for power and signal.
All leads must be wide and 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
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. One can also add a
serial resistor in order to minimise its influ-
ence.
One can add in parallel with feedback resistor
a few pF ceramic capacitor C
F
adjusted to
optimize the settling time.
