Pin Description

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.

CAP

FILT_CAP

External capacitor input used to filter VMX inputs

41,36,

21,16

VMX

Positive converter sense line, VMA through VMF

42,37,

32,27,

22,17

CAP

CAPX

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

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