Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT A | output | Output of amplifier A, rail-to-rail swing; short-circuit current is specified at 40 mA. |
| 2 | -IN A | input | Inverting input of amplifier A; input terminals are diode-clamped to the supply rails and signals beyond 0.5 V outside the rails must be limited to 10 mA or less. |
| 3 | +IN A | input | Non-inverting input of amplifier A; common-mode range is (V-)-0.1 V to (V+)+0.1 V. |
| 4 | V- | power_in | Negative supply rail; operates from +2.5 V to +5.5 V total supply (±1.25 V to ±2.75 V) and supply voltage above 7 V absolute maximum can permanently damage the amplifier. |
| 5 | +IN B | input | Non-inverting input of amplifier B; common-mode range is (V-)-0.1 V to (V+)+0.1 V. |
| 6 | -IN B | input | Inverting input of amplifier B; input terminals are diode-clamped to the supply rails and signals beyond 0.5 V outside the rails must be limited to 10 mA or less. |
| 7 | OUTB | output | Output of amplifier B, rail-to-rail swing; short-circuit current is specified at 40 mA. |
| 8 | V+ | power_in | Positive supply rail; operates from +2.5 V to +5.5 V total supply, with 7 V absolute maximum supply voltage. |
