Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT1 | output | Output of amplifier 1, which swings to within 50 mV of each rail for IOUT ≤ 100 µA and can source or sink 15 mA while 0.5 V from the supply rails. |
| 2 | -IN1 | input | Inverting input of amplifier 1, a JFET input with input bias current below 25 pA maximum; the input voltage range extends 0.2 V below −VS. |
| 3 | +IN1 | input | Non-inverting input of amplifier 1, a JFET input with input bias current below 25 pA maximum; the input voltage range extends 0.2 V below −VS. |
| 4 | -VS | power_in | Negative supply rail; the part operates from a single supply of 3.0 V to 36 V (with −VS as ground) or from dual supplies of ±1.5 V to ±18 V. |
| 5 | +IN2 | input | Non-inverting input of amplifier 2, a JFET input with input bias current below 25 pA maximum; the input voltage range extends 0.2 V below −VS. |
| 6 | -IN2 | input | Inverting input of amplifier 2, a JFET input with input bias current below 25 pA maximum; the input voltage range extends 0.2 V below −VS. |
| 7 | OUT2 | output | Output of amplifier 2, which swings to within 50 mV of each rail for IOUT ≤ 100 µA and can source or sink 15 mA while 0.5 V from the supply rails. |
| 8 | +VS | power_in | Positive supply rail; the part operates from a single supply of 3.0 V to 36 V or from dual supplies of ±1.5 V to ±18 V. |
