Description
12 ADC5/EXT_REF2IN− I Single-Ended or Differential Analog Input 5/External Reference Negative Input. This is a dual
function analog input pin. ADC5 serves as the analog input for the auxiliary ADC. EXT_REF2IN−
serves as the external reference negative input by ADC for the auxiliary channel.
13 ADC4/EXT_REF2IN+ I Multifunction Analog Input Pin. This pin can be used for the single-ended or differential
Analog Input 4, which is the analog input for the auxiliary ADC, or it can be used for the
external reference positive input for the auxiliary channel.
14 ADC3 I Single-Ended or Differential Analog Input 3. Analog input for the primary and auxiliary ADCs.
15
ADC2
I
Single-Ended or Differential Analog Input 2. Analog input for the primary and auxiliary ADCs.
16 IEXC1 O Programmable Current Source. Analog output pin.
17 IEXC0 O Programmable Current Source. Analog output pin.
18 GND_SW I Switch to Internal Analog Ground Reference. When this input pin is not used, connect it
directly to the AGND system ground.
19 ADC1 I Single-Ended or Differential Analog Input 1. Analog input for the primary ADC. Negative differential
input for primary ADC.
20 ADC0 I Single-Ended or Differential Analog Input 0. Analog input for the primary ADC. Positive differential
input for primary ADC.
21 VREF+ I External Reference Positive Input for the Primary Channel. Analog input pin.
22 VREF− I External Reference Negative Input for the Primary Channel. Analog input pin.
23 AGND S Analog Ground.
