Pinout

Pin	Name	Type	Function
1	1OUT	output	Output of channel 1; the output voltage range includes the negative supply rail, and the absolute maximum output current is ±30 mA per output.
2	1IN-	input	Inverting input of channel 1; the input must stay within the common-mode range of -0.2 V to 3.5 V at VDD = 5 V (-0.2 V to 8.5 V at VDD = 10 V) for the recommended operation.
3	1IN+	input	Non-inverting input of channel 1; the input must stay within the common-mode range of -0.2 V to 3.5 V at VDD = 5 V (-0.2 V to 8.5 V at VDD = 10 V) for the recommended operation.
4	VDD	power_in	Positive (highest) supply pin; recommended supply is 3 V to 16 V for the C suffix, with an absolute maximum of 18 V.
5	2IN+	input	Non-inverting input of channel 2; the input must stay within the common-mode range of -0.2 V to 3.5 V at VDD = 5 V (-0.2 V to 8.5 V at VDD = 10 V) for the recommended operation.
6	2IN-	input	Inverting input of channel 2; the input must stay within the common-mode range of -0.2 V to 3.5 V at VDD = 5 V (-0.2 V to 8.5 V at VDD = 10 V) for the recommended operation.
7	2OUT	output	Output of channel 2; the output voltage range includes the negative supply rail, and the absolute maximum output current is ±30 mA per output.
8	3OUT	output	Output of channel 3; the output voltage range includes the negative supply rail, and the absolute maximum output current is ±30 mA per output.
9	3IN-	input	Inverting input of channel 3; the input must stay within the common-mode range of -0.2 V to 3.5 V at VDD = 5 V (-0.2 V to 8.5 V at VDD = 10 V) for the recommended operation.
10	3IN+	input	Non-inverting input of channel 3; the input must stay within the common-mode range of -0.2 V to 3.5 V at VDD = 5 V (-0.2 V to 8.5 V at VDD = 10 V) for the recommended operation.
11	GND	power_in	Negative (lowest) supply or ground pin; the common-mode input range extends below this rail for the C and I suffix types.
12	4IN+	input	Non-inverting input of channel 4; the input must stay within the common-mode range of -0.2 V to 3.5 V at VDD = 5 V (-0.2 V to 8.5 V at VDD = 10 V) for the recommended operation.
13	4IN-	input	Inverting input of channel 4; the input must stay within the common-mode range of -0.2 V to 3.5 V at VDD = 5 V (-0.2 V to 8.5 V at VDD = 10 V) for the recommended operation.
14	4OUT	output	Output of channel 4; the output voltage range includes the negative supply rail, and the absolute maximum output current is ±30 mA per output.
