Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD1 | power_in | High-side isolated power supply input; operating range 4.5 V to 5.5 V nominal; absolute maximum 6 V. |
| 2 | VINP | input | Noninverting analog input; accepts differential input voltage ±250 mV relative to VINN; common-mode range GND1-0.16 V to VDD1 V. |
| 3 | VINN | input | Inverting analog input; accepts differential input voltage ±250 mV relative to VINP; common-mode range GND1-0.16 V to VDD1 V. |
| 4 | GND1 | power_in | High-side analog ground reference for isolated input stage; establishes potential reference for VINP, VINN, and VDD1. |
| 5 | GND2 | power_in | Low-side analog ground reference for isolated output stage; establishes potential reference for VOUTP, VOUTN, and VDD2. |
| 6 | VOUTN | output | Inverting analog output; provides differential gain of 8 with output impedance 2.5 Ω; common-mode voltage set by VDD2 (1.29 V at 3.3 V, 2.55 V at 5.0 V). |
| 7 | VOUTP | output | Noninverting analog output; provides differential gain of 8 with output impedance 2.5 Ω; common-mode voltage set by VDD2 (1.29 V at 3.3 V, 2.55 V at 5.0 V). |
| 8 | VDD2 | power_in | Low-side isolated power supply input; operating range 2.7 V to 5.5 V nominal; sets output stage common-mode voltage and filters. |
