DESCRIPTION

The TSH10 is a low cost wide bandwidth single
operational amplifier featuring low input noise of
6nV/√Hz. Otherfeaturesas unity gainstability,fast
settling time and high linearitymake it suitable for
any application requiring speed and precision as
high resolution videoor DAC buffer.

EVALUATION CIRCUIT

As for any high frequency device, a few rules must
be observedwhendesigningthe PCBto get the best
performancesfrom this high speed op amp.

From the mostto the least important points :

• Each power supply lead has to be bypassed
to ground with a 10nF ceramic capacitorvery
close to the device and a 10µF tantalum ca-
pacitor.

• Toprovidelow inductance and lowresistance
common return, use a ground plane or com­mon point return for powerand signal.

• All leads 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
constantwithparasiticcapacitance.Beaware

• Choose componentsizesassmallaspossible
(SMD).

• 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.

• One can add in parallelwithfeedbackresistor
