8-bit PIC^® Microcontrollers

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 100kbps) 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 100ksps 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 2mm 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 90dB SINAD.

Digital to Analog Converters

9-/8-bit DACs can provide an accurate reference to an on-board comparator module in closed-loop control applications such as lighting and motor control. With a variety of internal/external connection options, these DACs can also be used in conjunction with an Op Amp for signal generation duties.

5-bit DACs are our most cost effective DAC solution, and provides 32 distinct voltage output levels from rail-to-rail. The 5-bit DAC can be connected to an external pin or a number of modules internal to the device. This combination of flexibility and low cost provides an excellent platform for high power LED drive and simple power supply circuits.

High Speed Comparators

Comparators, have been included in the PIC Microcontroller line up for many years. We are now offering feature rich High Speed (50nS) variants to enable faster responding / more efficient closed loop feedback designs.

Op-Amps

Op-Amps are a basic building block in electronic design. Integrating Op-Amps into the Microcontroller offers increased flexibility and reliability while reducing BOM costs and board space. The Op-Amps used in our 8-bit family are great for analog control loops, sensor amplification, basic signal conditions, etc…

High Current Sink/Source Pins

High Current Sink/Source pins with the ability to sink/source 50mA the high currents pins enable direct MOSFET drive from the microcontroller.
