LM211DT from STMicroelectronics, in a SO-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 | GND | power_in | Ground reference pin; voltage between this pin and V_CC− (pin 4) must not exceed 30V absolute maximum. |
| 2 | IN+ | input | Non-inverting differential input; input bias current 100nA typ / 150nA max, common-mode range −14.5V to +13.8V with ±15V supply. |
| 3 | IN− | input | Inverting differential input; input bias current 100nA typ / 150nA max, common-mode range −14.5V to +13.8V with ±15V supply. |
| 4 | VCC− | power_in | Negative supply voltage pin; supply range 5V to ±15V, absolute maximum 36V total supply across VCC+ and VCC−. |
| 5 | BAL | passive | Balance pin used with pin 6 for output balance / offset null adjustment. |
| 6 | STROBE_BAL | input | Strobe and balance pin; strobe current 3mA max; strobe pin voltage must not exceed VCC+ − 5V absolute maximum. |
| 7 | OUT | output | Open-collector output; can switch up to 50V at 50mA, VOL ≤ 1.5V at IO = 50mA, high-level leakage IOH ≤ 10nA at VO = +35V (LM211). |
| 8 | VCC+ | power_in | Positive supply voltage pin; operating range +5V to +15V, absolute maximum 36V total supply; power dissipation 710mW max in SO-8. |
