Data Output Registers
Shunt Voltage Register 01h (Read-Only)
The Shunt Voltage Register stores the current shunt voltage reading, VSHUNT. Shunt Voltage Register bits are
shifted according to the PGA setting selected in the Configuration Register (00h). When multiple sign bits are
present, they will all be the same value. Negative numbers are represented in two's complement format.
Generate the two's complement of a negative number by complementing the absolute value binary number and
adding 1. Extend the sign, denoting a negative number by setting the MSB = '1'. Extend the sign to any
additional sign bits to form the 16-bit word.
Example: For a value of VSHUNT = –320 mV:
1. Take the absolute value (include accuracy to 0.01mV)==> 320.00
2. Translate this number to a whole decimal number ==> 32000
3. Convert it to binary==> 111 1101 0000 0000
4. Complement the binary result : 000 0010 1111 1111
5. Add 1 to the Complement to create the Two’s Complement formatted result ==> 000 0011 0000 0000
6. Extend the sign and create the 16-bit word: 1000 0011 0000 0000 = 8300h (Remember to extend the sign to
all sign-bits, as necessary based on the PGA setting.)
At PGA = ÷8, full-scale range = ±320 mV (decimal = 32000, positive value hex = 7D00, negative value hex =
8300), and LSB = 10 mV.
