SLDS204B October 2014 – June 2020 PGA300
PRODUCTION DATA.
When configured in current output mode, the OUT pin is driving the base of a bipolar junction transistor (BJT); see Figure 74. The COMP pin is connected to the emitter of the BJT and the FB+ pin is connected to the return terminal of the supply. The FB– pin is not used in current output mode.
To configure the PGA300 for current output mode set the following bits in the OP_STAGE_CTRL and DAC_CONFIG registers:
