Analog to Digital Converters

Successive Approximation Register (SAR)

The majority of our integrated ADCs are implemented with the SAR architecture. SAR is a natural fit for 8-bit MCUs as it is very low power and cost effective, while providing the require resolution and accuracy for 8-bit applications.

12-bit ADC is available on the PIC16F178x family, offering up to 14 channels at 75 ksps conversion rate. The module also supports a 10-bit mode, which can be used if higher sample rates (up to 100 kbps) are desired.

10-bit ADC can be found on over 200 8-bit PIC® MCUs ranging from 8 to 100 pins. With up to 25 channels at 100 ksps conversion rate, this ADC offers the best balance of cost and performance in 8-bit.

8-bit ADC is found on several cost-optimized 8-bit PIC MCU families (including the PIC10F2xx/3xx), brings intelligent analog capability into footprints as small as 2 x 3mm, with as few as 6 pins.

Delta Sigma

A select few of our 8-bit devices have ADCs based on a Delta-Sigma architecture. The Delta-Sigma architecture enables very high resolution and accuracy, at lower sampling rates.

16-bit ADC is available on the PIC18F8xJ72 family offering outstanding performance at 90 dB SINAD.
