The circuit illustrated is an 8-bit T-type resistor network D/A converter (DAC), whose core function is to convert digital signals into analog voltages through a resistor network. Below is a detailed analysis of the circuit logic: 1. Circuit Structure and Component Functions 1.1 Resistor Network: Utilizes an R-2R type resistor network, consisting of only two … Read more
A constant current source is a power supply that can provide a constant current to a load, making its application range very broad and essential in many cases. For example, when charging a battery with a typical charger, the charging current decreases as the terminal voltage of the battery gradually increases. To ensure constant current … Read more
