Design Simulations

Schematics used for simulation of TPL1401 used as sensitivity adjustments for microphone. In the following schematics, ADC is simulating the digital codes for the TPL1401. Simulation is done for DIGITPOT code changes from 118 to 138 ( in decimal) which corresponds to ADC input voltage of 2.3V to 2.7V.
