How many sensors can I implement using one AD7147 device?

The number of sensors that can be implemented using one AD7147 depends on the type of sensors required. The AD7147 has 13 CIN inputs, and has 12 time based conversion stages. The table below gives a the number of input pins and the number of conversion stages required for each sensor type. Any number of sensors can be combined, as long as the total number of inputs required does not exceed 13, and the total number of conversions required does not exceed 12.

Sensor Type	# CIN inputs	# conversion stages
Button	1	1 or 0.5
Keypad	1 per row & 1 per column	1 per row & 1 per column
Slider	2	2
Wheel	8	8
