Octal digital/analog converter circuit The figure shows the circuit diagram of the octal digital/analog converter. The circuit operates at 5V and provides eight output voltages. Each output voltage can be digitally adjusted between the mains (0~5V). The resolution of each output is 20mV / least significant bit. The digital-to-analog converter (DAC) has a "peak reserve" of 3.5V between Vd0 and the reference voltage. However, IC2 cancels this limitation by the 10V supply generated by Vd0. The reference voltage of all converters is connected to a 5V power supply. IC2 uses a 5V input voltage as an unregulated 10V output with an output impedance of less than 10Ω. It provides 100mA current so that 8 DACs give their maximum output current simultaneously. key chains,liquid keychains,custom pvc keychains,metal keychains,fancy key chains,custom key chains, keychain for kids,keychain for lady Shenzhen Konchang Electronic Technology Co.,Ltd , https://www.konchangs.com
