LMC7211BIMX 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 connection. |
| 2 | INVERTING INPUT | input | Inverting (−) comparator input; common-mode range extends beyond both supply rails (about −0.2V to V+ + 0.2V specified), with input current limited to ±5mA. |
| 3 | NON-INVERTING INPUT | input | Non-inverting (+) comparator input; common-mode range extends beyond both supply rails (about −0.2V to V+ + 0.2V specified), with input current limited to ±5mA. |
| 4 | V- | power_in | Negative supply, ground in single-supply use; total supply voltage V+ to V− is 2.7V to 15V (absolute maximum 16V). |
| 5 | NC | unconnected | No connection. |
| 6 | OUTPUT | output | Push-pull comparator output with 30mA typical source and 45mA typical sink short-circuit current; output current limited to ±30mA absolute maximum. |
| 7 | V+ | power_in | Positive supply, specified for 2.7V, 5V and 15V operation (2.7V to 15V range, 16V absolute maximum). |
| 8 | NC | unconnected | No connection. |
