18-bit ADC uses PC serial port

Here is a high resolution A/D converter from EDN Magazine that can be driven from a ubiquitous, 9-pin serial port.

16-bit ADC provides 19-bit resolution

PIC18F2550 MAX1241 1-Channel ADC

There are a number of advantages for utilizing an external analog to digital converter (ADC) in a project’s design. The internal ADC of the PIC18F series is limited to 10-bit resolution, while much higher resolution ADCs are available.

PIC18F2550 MAX144 2-Channel ADC

The MAX144 is a 12-bit two-channel ADC that has a 7.4µs successive-approximation ADC, automatic power-down, fast wake-up (2.5µs), an on-chip clock, and a high-speed, 3-wire serial interface.
