Dual CMOS op-amp with rail-to-rail input and output and a femtoamp-class input bias current, so it buffers high-impedance sources, like sensors and integrators, without loading them. It runs on a single or dual supply from 3 to 15 V and holds accuracy across the full input range. The wide supply span and low bias make it a common choice for pH probes, photodiodes, and other high-impedance front ends. A classic general-purpose CMOS dual.

Pinout

Pin	Name	Type	Function
1	OUT A	output	Output for amplifier A. Rail-to-rail output swing within 20mV of either supply on 100kΩ load; specified for 2kΩ and 600Ω loads. Max output current ±30mA (absolute max).
2	-IN A	input	Inverting input for amplifier A. CMOS input with ultra-low 20fA typical input bias current and 10TΩ input resistance. Absolute max input current ±5mA.
3	+IN A	input	Noninverting input for amplifier A. Rail-to-rail common-mode input voltage range (V- to V+). CMOS input with 20fA typical bias current.
4	V-	power_in	Negative supply voltage input (or GND in single-supply operation). Supply voltage VS = (V+) - (V-) from 3V (min) to 15.5V (nom max), 16V absolute max. Max supply pin current 40mA.
5	+IN B	input	Noninverting input for amplifier B. Rail-to-rail common-mode input voltage range. CMOS input, 20fA typical bias current, 10TΩ input resistance.
6	-IN B	input	Inverting input for amplifier B. CMOS input with 20fA typical bias current. Absolute max input current ±5mA.
7	OUT B	output	Output for amplifier B. Rail-to-rail output swing within 20mV of supply on 100kΩ load; drives 2kΩ and 600Ω loads. Absolute max output current ±30mA.
8	V+	power_in	Positive supply voltage input. Supply range VS = (V+) - (V-) is 3V to 15.5V (16V absolute max). Do not short output to V+ when V+ > 13V.
