Working Principles

The LTC2634HUD-HMI12#TRPBF operates by receiving digital input data through the SDA and SCL pins. The internal circuitry converts this digital information into an analog voltage output, which is available at the VOUT pin. The reference voltage provided at the REF pin determines the maximum output voltage. The LDAC and CLR inputs control the loading and clearing of the DAC register, respectively. The CS pin is used to select the device when multiple DACs are connected in a daisy-chain configuration.
