Ground. For thin QFN packages, also make an external connection from
GND to the under-side exposed paddle.
Adjustable Output Voltage Feedback Input. Connect a resistor-divider
between REFOUT, ADJ, and GND (MAX4069 only, see Functional Diagram).
Voltage Output. The difference voltage, V
the voltage difference between RS+ and RS- and indicates the correct
polarity.
Supply Voltage Input. Bypass V
Gain-Setting Input. Connect GSEL low to select gain = 50V/V, or connect
GSEL high to select gain = 100V/V.
