Offering one of the most comprehensive sets of peripherals in the industry, the PIC16C781 and Markets for the PIC16C781 and PIC16C782 include PIC16C782 allow customers to reduce the number of almost any application where there is some form of components required to implement embedded control closed loop control, which can utilize firmware or functions. hardware control.

An example application would be switch mode power supply designs where the PSMC can be used for switching control, the DAC for voltage set point, and the ADC, opera- tional amplifier and comparators to monitor and control the stability and loop dynamics.

Other applications for the PIC16C78X devices include: motor speed control, UPS, power inverters, signal generation, audio applica- tions, general sensor interfaces and battery chargers.

The operational amplifier has programmable gain bandwidth product (GBWP), auto-cali- bration to minimize input offset voltage, rail- to-rail output and ultra low leakage inputs.
