Pinout

Pin	Name	Type	Function
1	OUT A	output	Channel A output is rail-to-rail AB-class, drives loads down to 10 kΩ to V+ or ground, and the datasheet specifies a short-circuit current of ±15 mA at VS=5.5 V.
2	-IN A	input	Channel A inverting input must stay within (V-)-0.5 V to (V+)+0.5 V, and input current should be limited to 10 mA when the input is driven beyond a supply rail by more than 0.5 V.
3	+IN A	input	Channel A non-inverting input has a common-mode range that extends about 200 mV beyond both supply rails, with CMRR, PSRR, offset and THD possibly degrading in the crossover region near (V+)-1.3 V.
4	V+	power_in	Positive supply, rated 1.8 V to 5.5 V (±0.9 V to ±2.75 V), and the datasheet recommends bypassing it with a 0.01 µF ceramic capacitor.
5	+IN B	input	Channel B non-inverting input has the same rail-to-rail common-mode range as the other channels, extending about 200 mV beyond both supply rails.
6	-IN B	input	Channel B inverting input must stay within (V-)-0.5 V to (V+)+0.5 V, with input current limited to 10 mA when overdriven beyond a supply rail.
7	OUT B	output	Channel B output is rail-to-rail AB-class, drives loads down to 10 kΩ to V+ or ground, and is short-circuit-limited to ±15 mA at VS=5.5 V.
8	OUT C	output	Channel C output is rail-to-rail AB-class, drives loads down to 10 kΩ to V+ or ground, and is short-circuit-limited to ±15 mA at VS=5.5 V.
9	-IN C	input	Channel C inverting input must stay within (V-)-0.5 V to (V+)+0.5 V, with input current limited to 10 mA when overdriven beyond a supply rail.
10	+IN C	input	Channel C non-inverting input has the same rail-to-rail common-mode range as the other channels, extending about 200 mV beyond both supply rails.
11	V-	power_in	Negative supply rail, used as ground in single-supply operation, to which all input and output voltage limits are referenced.
12	+IN D	input	Channel D non-inverting input has the same rail-to-rail common-mode range as the other channels, extending about 200 mV beyond both supply rails.
13	-IN D	input	Channel D inverting input must stay within (V-)-0.5 V to (V+)+0.5 V, with input current limited to 10 mA when overdriven beyond a supply rail.
14	OUT D	output	Channel D output is rail-to-rail AB-class, drives loads down to 10 kΩ to V+ or ground, and is short-circuit-limited to ±15 mA at VS=5.5 V.
