Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT A | output | Output of amplifier A, which is rail-to-rail; the datasheet gives a short-circuit current of 13 mA at VSY = 1.8 V. |
| 2 | -IN A | input | Inverting input of amplifier A; the input voltage should stay within ±VSY ± 0.3 V, and the voltage difference between the two inputs must not exceed ±VSY. |
| 3 | +IN A | input | Non-inverting input of amplifier A; the input voltage should stay within ±VSY ± 0.3 V, and the voltage difference between the two inputs must not exceed ±VSY. |
| 4 | V- | power_in | Negative supply pin; the amplifiers are powered from a single supply of 1.8 V to 5.5 V, with a 6 V absolute maximum supply voltage. |
| 5 | +IN B | input | Non-inverting input of amplifier B; the input voltage should stay within ±VSY ± 0.3 V, and the voltage difference between the two inputs must not exceed ±VSY. |
| 6 | -IN B | input | Inverting input of amplifier B; the input voltage should stay within ±VSY ± 0.3 V, and the voltage difference between the two inputs must not exceed ±VSY. |
| 7 | OUT B | output | Output of amplifier B, which is rail-to-rail; the datasheet gives a short-circuit current of 13 mA at VSY = 1.8 V. |
| 8 | V+ | power_in | Positive supply pin; the amplifiers are powered from a single supply of 1.8 V to 5.5 V, with a 6 V absolute maximum supply voltage. |
