DESCRIPTION

The TSH11 is a low cost wide bandwidth single
operationalamplifier featuring extremely lowinput
current of 2pA typ. Other features as unity gain
stability,fast settlingtime and highlinearity make it
suitable formanyapplicationsrequiringspeedand
very high input impedance as photo cell amplifier,
high inputimpedancebuffer,Fetprobe, highspeed
precisionintegrator,sample andhold circuit...

EVALUATION CIRCUIT

As for any high frequencydevice, a fewrules must
be observedwhendesigningthe PCBtoget the 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 witha 10nF ceramic capacitor very
close to the device and a 10µF tantalum ca-
pacitor.

• To provide low inductance and low resistance
common return, use a ground plane or com­mon point return for power and signal.

• Allleads must be wide and as short as possi­ble especially for op amp inputs. This is in
order to decrease parasitic capacitance and

inductance.

• Use small resistor values to decrease time
constantwith parasiticcapacitance.

• Choosecomponentsizesassmall aspossible
(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 canadd in parallelwith feedbackresistor
a few pF ceramic capacitor C
