Working Principles

The TLV5638IDR is a digital-to-analog converter that converts digital signals into corresponding analog voltages. It utilizes a 12-bit resolution to provide precise output levels. The digital input data (DIN) is received and processed by the IC, which then generates the corresponding analog voltage at the output pin (OUT). The chip select (CS) pin is used to enable or disable the device.
