Description
53 VCOM
O
Internal Reference voltage
Connect a stabilizing capacitor between AVSS and this pin
54 CCDIN2 I
Sensor signal input
55 REFIN2 I
Reference input
Connect a same value capacitor as CCDIN2 input capacitor between
AVSS and this pin.
In DC direct-coupled mode, an externally-fed signal reference level
should be input.
56 REFIN3 I
Reference input
Connect a same value capacitor as CCDIN3 input capacitor between
AVSS and this pin.
IN DC direct-coupled mode, an externally-fed signal reference level
should be input.
57 CCDIN3 I
Sensor signal input
58 VRP
O
ADC reference voltage positive side
Connect a stabilizing capacitor between AVSS and this pin.
59 VRN
O
ADC reference voltage negative side
Connect a stabilizing capacitor between AVSS and this pin.
60 CCDIN4 I
Sensor signal input
61 REFIN4 I
Reference input
Connect a same value capacitor as CCDIN4 input capacitor between
AVSS and this pin.
In DC direct-coupled mode, an externally-fed signal reference level
should be input.
62 REFIN5 I
Reference input
Connect a same value capacitor as CCDIN5 input capacitor between
AVSS and this pin.
In DC direct-coupled mode, an externally-fed signal reference level
should be input.
63 CCDIN5 I
Sensor signal input
64 AVDD
PWR Analog power supply
Type description
I : input pin
O : output pin PWR : power supply pin
