The overall gain of the amplifier is controlled digitally by the UP and DOWN terminals. At power up, the gain is set at the lowest level which is -85dB. It can then be adjusted to any of 31 discrete steps by pulling the voltage down at the desired pin to logic low. The gain is adjusted in the initial stage of the amplifier as opposed to the

Week #1: Audio amplifier Week #2: Microphone circuit The audio amplifier project is more difficult and time-consuming than the microphone pre-amp, so part of week #2 may be used to finish the audio amp. All breadboarding and testing can and should be done in lab. Soldering and hardwiring can and should be done outside lab.

Digital potentiometers can have up to 50 - 100pF of parasitic capacitance to ground, which may alter frequency characteristics of the amplifier when used in the feedback net. And the shape will change with trimpot value. If used as input divider with a fixed-gain amp, you will have more unnecessary noise.
