A comparator is an electronic circuit, which compares the two inputs that are applied to it and produces an output. The output value of the comparator . An operational amplifier (op amp) is an analog circuit block that takes a differential voltage input and produces a single-ended voltage output Interfaces ICs are used as data transformation between microcontroller and peripheral ICs such as sensors, ADCs, DACs 

Operational Amplifiers – Nano Power, Micro-power, High speed, and high precision. Comparators – Single / Dual / quad Nano Power, High speed – SC70-5, SOT23-5, Soic-8, TSSOP-14 LDO – Low dropout , Enable mode , SOT23-5, low IQ, Iout=300mA, Vout= 1.8V, 2.8V. 3V, 3.3V DAC and ADC, high speed , high precision 8bit- 16bit ; MSOP-8 / TSSOP-16 Audio/Video Buffers and Filters 1~6 channels up to 72MHz RS232 / RS485 drivers ESD protected Current Sense Amplifier Analog Switch Audio Line Drivers Video Filter Drivers Power Sequencer Switching Power Regulator Voltage Supervisors & Reset IC's Voltage Reference Li-on Battery Charger Motor Driver
