... AMIS-14935 Audio Amplifier Using AMIS-14935 in Hearing Assist Applications Notes: 1. When using volume control potentiometer, keep input resistor between 25kOhm to 50kOhm for optimum performance. Using lower than 25k may cause higher distortion and using higher than 50k may cause output noise to increase. ...

... 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 ...
