NAME
MAX4072
FUNCTION
1
SHDN Shutdown Input. Drive SHDN low to select shutdown mode. Connect SHDN
to VCC for normal operation.
2
RS- Negative Connection to the External Sense Resistor
3
RS+ Positive Connection to the External Sense Resistor
—
N.C. No Connection. Not internally connected.
4
GND
Ground. For thin QFN packages, also make an external connection from
GND to the under-side exposed paddle.
—
ADJ
Adjustable Output Voltage Feedback Input. Connect a resistor-divider
between REFOUT, ADJ, and GND (MAX4069 only, see Functional Diagram).
—
REFOUT Reference Output Voltage (MAX4069/MAX4070/MAX4071)
Voltage Output. The difference voltage, VOUT - VREF, is proportional to
6
OUT the voltage difference between RS+ and RS- and indicates the correct
polarity.
7
VCC Supply Voltage Input. Bypass VCC to GND with a 0.1µF capacitor.
8
GSEL
Gain-Setting Input. Connect GSEL low to select gain = 50V/V, or connect
GSEL high to select gain = 100V/V.
