I/O

VREF_CNTL

Voltage reference input used for DC output control and margining.

VREF_CNTL can be programmed to output the internal 1.25V reference.

15

CAP

FILT_CAP

External capacitor input used to filter VMX inputs

IN

VMX

Positive converter sense line, VMA through VMD

42,37,

32,27

CAP

CAPX

External capacitor input used to filter the VMX inputs to the 10-bit ADC, CAPA

through CAPD. This provides an RC filter where R = 25kΩ.
