Pinout
8| Pin | Name | Functions | Notes |
|---|---|---|---|
| 1 | EMIT OUT | GPIO | Output emitter of the comparator output transistor. |
| 2 | IN+ | GPIO | Noninverting comparator input. |
| 3 | IN- | GPIO | Inverting comparator input. |
| 4 | VCC- | POWERGND | Negative supply (ground for single-supply operation). |
| 5 | BALANCE | GPIO | Offset balance pin for external offset adjustment. |
| 6 | BAL/STRB | GPIO | Balance/strobe pin; driving the strobe forces the output off. |
| 7 | COL OUT | GPIO | Open-collector comparator output. |
| 8 | VCC+ | POWER | Positive supply. |
