Pinout

Pin	Name	Type	Function
1	IN1	input	Amplifier 1 input (internal gain of 2); input range VEE to VCC - 1.75V, with ESD diodes to the supplies so input current should be limited to 10mA or less.
2	IN2	input	Amplifier 2 input (internal gain of 2); input range VEE to VCC - 1.75V, with ESD diodes to the supplies so input current should be limited to 10mA or less.
3	IN3	input	Amplifier 3 input (internal gain of 2); input range VEE to VCC - 1.75V, with ESD diodes to the supplies so input current should be limited to 10mA or less.
4	GND	power_in	Ground pin connected to the gain-setting resistors RG of the LT6550 amplifiers; VGND = 0V in the ±5V specifications.
5	VEE	power_in	Negative supply, 0V for single-supply operation; fused to the lead frame for heat sinking, with total supply (VCC to VEE) up to 12.6V.
6	N/C	unconnected	No internal connection.
7	OUT3	output	Amplifier 3 rail-to-rail output with gain of 2, drives 60mA, with short-circuit protection of indefinite duration.
8	OUT2	output	Amplifier 2 rail-to-rail output with gain of 2, drives 60mA, with short-circuit protection of indefinite duration.
9	OUT1	output	Amplifier 1 rail-to-rail output with gain of 2, drives 60mA, with short-circuit protection of indefinite duration.
10	VCC	power_in	Positive supply, minimum 3V, with total supply voltage (VCC to VEE) up to 12.6V.
