Pinout

Pin	Name	Type	Function
1	OUT A	output	Output of amplifier A, which swings to within 10mV of V- and sources or sinks up to 20mA, and which needs a 0.22μF capacitor in series with 150Ω to drive loads from 200pF up to 10,000pF.
2	-IN A	input	Inverting input of amplifier A, with an input range of 0.3V to 44V for the LT1490AH and internal 1kΩ series resistors protecting it for faults up to 15V below V-.
3	+IN A	input	Non-inverting input of amplifier A, with an input range of 0.3V to 44V for the LT1490AH and internal 1kΩ series resistors protecting it for faults up to 15V below V-.
4	V-	power_in	Negative supply pin, which should be bypassed with about 0.01μF within an inch of the pin when split supplies are used and which tolerates reverse battery voltages up to 18V.
5	+IN B	input	Non-inverting input of amplifier B, with an input range of 0.3V to 44V for the LT1490AH and internal 1kΩ series resistors protecting it for faults up to 15V below V-.
6	-IN B	input	Inverting input of amplifier B, with an input range of 0.3V to 44V for the LT1490AH and internal 1kΩ series resistors protecting it for faults up to 15V below V-.
7	OUT B	output	Output of amplifier B, which swings to within 10mV of V- and sources or sinks up to 20mA, and which needs a 0.22μF capacitor in series with 150Ω to drive loads from 200pF up to 10,000pF.
8	V+	power_in	Positive supply pin, which operates over a total supply of 2V to 44V and should be bypassed with about 0.01μF within an inch of the pin, with the supply rising to its final voltage in no less than 1μs when total supply is 20V or more.
