7.2.1 Design Requirements

Assume a portable application requires the use of a 12-bit SAR ADC with acquisition time (tAQ) of 1µs and sample and hold capacitance (CSH) of 80pF.

The ADC runs on a single supply voltage of 5V and has a full scale input of 2.5VPP. A total harmonic distortion plus noise (THD+N) of less than –80dB is required to maintain signal fidelity. Determine if the LM7332 is a practical drive amplifier and find the values of Rflt and Cflt.
