Two of the most common analog building blocks used today are the
inverting and non-inverting amplifier. For these circuits, the two
most critical parameters of concern to designers are gain (G0) and
frequency response (fc), which are determined by external
resistors and capacitors.

By replacing the external fixed resistors with Xicor XDCPs,
designers now have a programmable voltage amplifier that can be
directly programmed using a microcontroller or microprocessor…The
Analog is On The Bus!
