NAME
FUNCTION
Supply Monitor Input 2. IN2 is internally sampled by the ADC. It is configurable for unipolar/
IN2
bipolar and single-ended/pseudo-differential. In pseudo-differential mode, IN1 and IN2 form
the + and - of the differential pair. Each input must stay within the specified ADC IN_ voltage
range.
Supply Monitor Input 3. IN3 is internally sampled by the ADC. It is configurable for unipolar/
IN3
bipolar and single-ended/pseudo-differential. In pseudo-differential mode, IN3 and IN4 form
the + and - of the differential pair. Each input must stay within the specified ADC IN_ voltage
range.
Supply Monitor Input 4. IN4 is internally sampled by the ADC. It is configurable for unipolar/
IN4
bipolar and single-ended/pseudo-differential. In pseudo-differential mode, IN3 and IN4 form
the + and - of the differential pair. Each input must stay within the specified ADC IN_ voltage
range.
N.C. No Connection. Leave unconnected. Do not use.
GND
IN5
Ground. Connect all GND pins together.
Supply Monitor Input 5. IN5 is internally sampled by the ADC. It is configurable for unipolar/
bipolar and single-ended/pseudo-differential. In pseudo-differential mode, IN5 and IN6 form
the + and - of the differential pair. Each input must stay within the specified ADC IN_ voltage
range.
Supply Monitor Input 6. IN6 is internally sampled by the ADC. It is configurable for unipolar/
IN6
bipolar and single-ended/pseudo-differential. In pseudo-differential mode, IN5 and IN6 form
the + and - of the differential pair. Each input must stay within the specified ADC IN_ voltage
range.
Supply Monitor Input 7. IN7 is internally sampled by the ADC. It is configurable for unipolar/
IN7
bipolar and single-ended/pseudo-differential. In pseudo-differential mode, IN7 and IN8 form
the + and - of the differential pair. Each input must stay within the specified ADC IN_ voltage
range.

Supply Monitor Input 8. IN8 is internally sampled by the ADC. It is configurable for unipolar/
bipolar and single-ended/pseudo-differential. In pseudo-differential mode, IN7 and IN8 form
the + and - of the differential pair. Each input must stay within the specified ADC IN_ voltage
range.
Configurable General-Purpose Input/Output 1
Configurable General-Purpose Input/Output 2
ADC Reference Bypass. RBP is an internally generated 1.4V reference for the ADC. Bypass
RBP to GND with a 2.2µF capacitor. Do not use RBP to power any additional circuitry.
SMBus Serial-Data, Open-Drain Input/Output
SMBus Serial-Clock Input
A0
SMBus Address Input 0. Connect to DBP, GND, or leave unconnected to select the desired
device address.
A1
SMBus Address Input 1. Connect to DBP, GND, or leave unconnected to select the desired
device address.
