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 10µF tantalum capacitor. ❑ To provide low inductance and low resistance common return, use a ground plane or common point return for power and 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. ) s t( ❑ 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. You can also add a serial resistor in order to minimise its influence. ❑ One can add in parallel with feedback resistor a few pF ceramic capacitor CF adjusted to optimize the settling time. TSH10 PACKAGE MECHANICAL DATA 8 PINS - PLASTIC MICROPACKAGE (SO) ) s t( c u d e t le o s b -O Millimeters Dim.
