Based on 8-bit platform, Series PIC16(L)F1769 comprises intelligent analog and digital peripherals, including tri-state op amps, 10-bit ADCs, 5- and 10-bit DACs, 10- and 16-bit PWMs, and high-speed comparators, along with two 100 mA I/Os. Programmable Ramp Generator provides real-time responses to system change, without CPU interaction for multiple independent channels. Hardware-based LED dimming control function is enabled by interconnections of Data Signal Modulator, op amp, and 16-bit PWM.
