APPLICATION CIRCUIT
SINGLE ENDED INPUT
Notes:
1. * = Not stuffed
2. Add a circuit (Cf) if needed, it can be a low filter to delete high frequency oscillation, but must to
avoid incorrect Rf and Cf combination to cause “glide” before 20KHz. In general Rf=20KΩ,
Cf=25pF, -3dB is 320KHz is recommended.
