Pinout

Pin	Name	Type	Function
1	OUTA	output	Output of channel A op-amp. Rail-to-rail output; short-circuit current typ. 130mA; diode-clamped to supply rails, limit to 140mA if driven beyond rails.
2	-INA	input	Inverting input of channel A op-amp. Rail-to-rail input, common-mode range -0.1V to +5.6V at Vs=5.5V; diode-clamped to supply rails, limit to 10mA if driven beyond rails.
3	+INA	input	Noninverting input of channel A op-amp. Rail-to-rail input, common-mode range -0.1V to +5.6V at Vs=5.5V; diode-clamped to supply rails, limit to 10mA if driven beyond rails.
4	V+	power_in	Positive (highest) power supply. Single-supply 2.5V to 5.5V or dual-supply +1.25V to +2.75V referenced to V-. Absolute max Vs = (V+)-(V-) = 7V. Bypass with a 0.1uF capacitor close to the pin.
5	+INB	input	Noninverting input of channel B op-amp. Rail-to-rail input, common-mode range -0.1V to +5.6V at Vs=5.5V; diode-clamped to supply rails, limit to 10mA if driven beyond rails.
6	-INB	input	Inverting input of channel B op-amp. Rail-to-rail input, common-mode range -0.1V to +5.6V at Vs=5.5V; diode-clamped to supply rails, limit to 10mA if driven beyond rails.
7	OUTB	output	Output of channel B op-amp. Rail-to-rail output; short-circuit current typ. 130mA; diode-clamped to supply rails, limit to 140mA if driven beyond rails.
8	OUTC	output	Output of channel C op-amp. Rail-to-rail output; short-circuit current typ. 130mA; diode-clamped to supply rails, limit to 140mA if driven beyond rails.
9	-INC	input	Inverting input of channel C op-amp. Rail-to-rail input, common-mode range -0.1V to +5.6V at Vs=5.5V; diode-clamped to supply rails, limit to 10mA if driven beyond rails.
10	+INC	input	Noninverting input of channel C op-amp. Rail-to-rail input, common-mode range -0.1V to +5.6V at Vs=5.5V; diode-clamped to supply rails, limit to 10mA if driven beyond rails.
11	V-	power_in	Negative (lowest) power supply. Ground in single-supply operation, or -1.25V to -2.75V in dual-supply operation. Bypass with a 0.1uF capacitor close to the pin.
12	+IND	input	Noninverting input of channel D op-amp. Rail-to-rail input, common-mode range -0.1V to +5.6V at Vs=5.5V; diode-clamped to supply rails, limit to 10mA if driven beyond rails.
13	-IND	input	Inverting input of channel D op-amp. Rail-to-rail input, common-mode range -0.1V to +5.6V at Vs=5.5V; diode-clamped to supply rails, limit to 10mA if driven beyond rails.
14	OUTD	output	Output of channel D op-amp. Rail-to-rail output; short-circuit current typ. 130mA; diode-clamped to supply rails, limit to 140mA if driven beyond rails.
