For gain 10 compensation may be simplified by removing C2 C3 and

adding a 200 pF capacitor (C4) between Lead 7 and 10

Closed Loop Voltage Gain

TLH10059 – 10

Layout Instructions

Layout

The layout should be such that stray capacitance

is minimal

Supplies

The supplies should be adequately bypassed

Used of 01 mF high quality ceramic capacitors is recom-

mended

Ringing

Excessive ringing (long acquisition time) may oc-

cur with large capacitive loads This may be reduced by

isolating the capacitive load with a resistance of 100X

Large source resistances may also give rise to the same

problem and this may be decreased by the addition of a

capacitance across the feedback resistance A value of

around 50 pF for unity gain configuration and around 30 pF

for gain 10 should be adequate

Latch Up

This may occur when the amplifier is used as a

voltage follower The inclusion of a diode between leads 6

and 2 with the cathode toward lead 2 is the recommended

preventive measure
