LM2900DR from Texas Instruments, in a SOIC-14. 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 | 1IN+ | input | Non-inverting (current-mirror) input of amplifier 1; negative input current should be limited externally to about -1 mA. |
| 2 | 2IN+ | input | Non-inverting (current-mirror) input of amplifier 2; negative input current should be limited externally to about -1 mA. |
| 3 | 2IN- | input | Inverting input of amplifier 2; input currents are differenced here and flow through the external feedback resistor, with negative input current limited to about -1 mA. |
| 4 | 2OUT | output | Output of amplifier 2; short circuit to ground is unlimited in duration at or below 25°C, but shorts to VCC can cause destructive heating. |
| 5 | 1OUT | output | Output of amplifier 1; short circuit to ground is unlimited in duration at or below 25°C, but shorts to VCC can cause destructive heating. |
| 6 | 1IN- | input | Inverting input of amplifier 1; input currents are differenced here and flow through the external feedback resistor, with negative input current limited to about -1 mA. |
| 7 | GND | power_in | Network ground terminal; all voltages are referenced to it, and input clamps hold inputs to about -0.3 V below it. |
| 8 | 3IN- | input | Inverting input of amplifier 3; input currents are differenced here and flow through the external feedback resistor, with negative input current limited to about -1 mA. |
| 9 | 3OUT | output | Output of amplifier 3; short circuit to ground is unlimited in duration at or below 25°C, but shorts to VCC can cause destructive heating. |
| 10 | 4OUT | output | Output of amplifier 4; short circuit to ground is unlimited in duration at or below 25°C, but shorts to VCC can cause destructive heating. |
| 11 | 4IN- | input | Inverting input of amplifier 4; input currents are differenced here and flow through the external feedback resistor, with negative input current limited to about -1 mA. |
| 12 | 4IN+ | input | Non-inverting (current-mirror) input of amplifier 4; negative input current should be limited externally to about -1 mA. |
| 13 | 3IN+ | input | Non-inverting (current-mirror) input of amplifier 3; negative input current should be limited externally to about -1 mA. |
| 14 | VCC | power_in | Positive supply; recommended 4.5 V to 32 V single supply, absolute maximum 36 V. |
