TLV3491AIDR from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No internal connection; can be left floating. |
| 2 | -IN | input | Inverting input; common-mode voltage range (V-) - 0.2 V to (V+) + 0.2 V. |
| 3 | +IN | input | Noninverting input; common-mode voltage range (V-) - 0.2 V to (V+) + 0.2 V. |
| 4 | V- | power_in | Negative (lowest) power supply; supply voltage range 1.8 V to 5.5 V. |
| 5 | NC | unconnected | No internal connection; can be left floating. |
| 6 | OUT | output | Comparator output; VOH 90-200 mV from rail or VOL 160-200 mV from rail at IOUT = 5 mA. |
| 7 | V+ | power_in | Positive (highest) power supply; supply voltage range 1.8 V to 5.5 V. |
| 8 | NC | unconnected | No internal connection; can be left floating. |
