... The AS1976/AS1977 requires proper layout and design techniques for optimum performance. Power-supply bypass capacitors are not typically required, although 100nF bypass capacitors should be placed ! close to the AS1976/AS1977 supply pins when supply impedance is high, leads are long, or for excessive noise on the supply lines. ! Minimize signal trace lengths to reduce stray capacitance ...
