The DAC Channel 1 output can be accessed through pin PA4—but PA4 is not extended to the ouput connector on the STM32L476G-Discovery board. To get the signal to the output connector, DAC Channel 1 is internally configured to drive OPAMP1. This opamp is used to drive PA3 (which is extended on the discovery board).
