AMIS-14935 Audio Amplifier
Using AMIS-14935 as Receiver Driver in H-aid
Ultra Low Power Audio System
Notes:
1. For optimum noise and distortion performance a 50k input
resistor is recommended.
2. Input coupling capacitor (C2) must be present. Forms a
high pass filter together with resistor R1 with an approximate
corner frequency of 1/(2*3.14*R1*C2).
3. Bypass capacitor (C1) may or may not be needed
dependent on the supply quality. This capacitor shall have a
low value (less than 1µF) since a high value capacitance
supply to ground may cause audible noise at power down. If
other parts of the system requires a higher capacitor value this
capacitor can be placed on the battery side of the switch
making the total stored charge on the supply line small when
system is powered down (switch is opened).
