Schematic diagram of programmable resistor The circuit schematic of the composite resistor is shown in the figure, which consists of an input op amp, a D/A converter, an analog switch, an output op amp, and an offset zeroing circuit. The input voltage value applied to one end of the standard resistor is buffer amplified, proportionally adjusted, and fed back to the other end of the standard resistor to control the input current to determine the input resistance value. The touch monitor is a product developed and designed by ourselves. It has been sold for more than 6 years and has exceeded 160,000 units. At present, it is running very well. It mainly customizes different touch technologies, different sizes, different interfaces, connecting cables and power supply parts to meet the needs of guests. We provide customers with the choice of Resistive Touch Screen, Capacitive Touch Screen, infrared Touch Screen and nano Touch Foil , and customize various interfaces for customers, such as: VGA, DVI, HDMI, DP and so on. It is mainly used in banks, hospitals, government units, airports, railway stations, supermarkets, real estate and other places.
