Working Principles

The LE9500DBJC is a digital-to-analog converter that converts digital signals into corresponding analog voltage or current outputs. It utilizes a 12-bit resolution to provide precise conversion results. The input digital data is received through the DIN pin and synchronized with the SCLK signal. The CS pin is used to select the chip for data transfer.

Upon receiving the digital data, the LE9500DBJC internally converts it into an analog voltage or current, which is available at the VOUT pin. The reference voltage provided at the VREF pin determines the output range of the DAC. The LDAC pin allows for simultaneous updating of multiple DACs in a system.
