Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT A | output | Output of amplifier A; the datasheet specifies a short-circuit to ground duration of indefinite (absolute maximum ratings table). |
| 2 | -IN A | input | Inverting input of amplifier A; input voltage should not exceed the supply rails by more than 0.3 V, and input current should be limited to below 5 mA using a series resistor if higher voltages are applied. |
| 3 | +IN A | input | Non-inverting input of amplifier A; the input common-mode range spans the full supply range (rail-to-rail input), with the same 0.3 V over-voltage and 5 mA input current limits as -IN A. |
| 4 | V- | power_in | Negative supply rail; the absolute maximum total supply voltage is 6 V and the operating supply range is stated as 2.7 V to 5.5 V in the features section. |
| 5 | +IN B | input | Non-inverting input of amplifier B; the input common-mode range spans the full supply range (rail-to-rail input), with the same 0.3 V over-voltage and 5 mA input current limits as the other inputs. |
| 6 | -IN B | input | Inverting input of amplifier B; input voltage should not exceed the supply rails by more than 0.3 V, and input current should be limited to below 5 mA using a series resistor if higher voltages are applied. |
| 7 | OUT B | output | Output of amplifier B; the datasheet specifies a short-circuit to ground duration of indefinite (absolute maximum ratings table). |
| 8 | V+ | power_in | Positive supply rail; the absolute maximum total supply voltage is 6 V and the operating supply range is stated as 2.7 V to 5.5 V in the features section. |
