8.2.2.12 Selecting the Resistor of Gain pin

The GAIN pin can be configured as both input and output. If the GAIN pin is configured as output pin, TI recommends that it be directly connected with the external I/O.

If the pin is configured as the input pin to select the current mirror ratio, the pull up or pull down resistor must be lower than 1-kΩ as there is an internal 5-kΩ resistor on the GAIN pin.
