Table 6. Pin Function Descriptions
Mnemonic
Function
VINP1
Analog Input to the inverting input amplifier on Channel 1’s positive input.
VFBP1
Feedback Connection from the output of the inverting amplifier on Channel 1’s positive input. When the input amplifiers are
bypassed, this pin allows direct access to the positive input of Channel 1’s sigma-delta modulator.
VINN1
Analog Input to the inverting input amplifier on Channel 1’s negative input.
VFBN1
Feedback connection from the output of the inverting amplifier on Channel 1’s negative input. When the input amplifiers are
bypassed, this pin allows direct access to the negative input of Channel 1’s sigma-delta modulator.
REFOUT
Buffered Reference Output, which has a nominal value of 1.2 V.
REFCAP
A bypass capacitor to AGND2 of 0.1 F is required for the on-chip reference. The capacitor should be fixed to this pin.
AVDD2
Analog Power Supply Connection.
AGND2
Analog Ground/Substrate Connection2.
DGND
Digital Ground/Substrate Connection.
DVDD
Digital Power Supply Connection.
RESET
Active Low Reset Signal. This input resets the entire chip, resetting the control registers and clearing the digital circuitry.
