Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN1+ | input | Non-inverting input of amplifier 1, rail-to-rail with common mode range Vcc- - 0.1 V to Vcc+ + 0.1 V. |
| 2 | VCC+ | power_in | Positive supply, operating range 1.5 V to 5.5 V (absolute maximum 6 V). |
| 3 | NC | unconnected | No internal connection. |
| 4 | IN2+ | input | Non-inverting input of amplifier 2, rail-to-rail with common mode range Vcc- - 0.1 V to Vcc+ + 0.1 V. |
| 5 | IN2- | input | Inverting input of amplifier 2, rail-to-rail with input current limited to 10 mA. |
| 6 | OUT2 | output | Rail-to-rail output of amplifier 2, typically 5 mA sink and source at 1.8 V supply. |
| 7 | OUT3 | output | Rail-to-rail output of amplifier 3, typically 5 mA sink and source at 1.8 V supply. |
| 8 | IN3- | input | Inverting input of amplifier 3, rail-to-rail with input current limited to 10 mA. |
| 9 | IN3+ | input | Non-inverting input of amplifier 3, rail-to-rail with common mode range Vcc- - 0.1 V to Vcc+ + 0.1 V. |
| 10 | NC | unconnected | No internal connection. |
| 11 | VCC- | power_in | Negative supply or ground reference for the amplifiers. |
| 12 | IN4+ | input | Non-inverting input of amplifier 4, rail-to-rail with common mode range Vcc- - 0.1 V to Vcc+ + 0.1 V. |
| 13 | IN4- | input | Inverting input of amplifier 4, rail-to-rail with input current limited to 10 mA. |
| 14 | OUT4 | output | Rail-to-rail output of amplifier 4, typically 5 mA sink and source at 1.8 V supply. |
| 15 | OUT1 | output | Rail-to-rail output of amplifier 1, typically 5 mA sink and source at 1.8 V supply. |
| 16 | IN1- | input | Inverting input of amplifier 1, rail-to-rail with input current limited to 10 mA. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
