AD780ARZ-REEL7 from Analog Devices, 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; the datasheet marks this pin NC (no connect). |
| 2 | +VIN | power_in | Positive supply input, specified from 4.0 V to 36 V, with a 36 V absolute maximum to ground. |
| 3 | TEMP | output | Temperature output of about 560 mV at 25°C with a sensitivity of about 2 mV/°C, which must be buffered because drawing current from it shifts VOUT. |
| 4 | GND | power_in | Ground reference for the device; it is grounded in the specified series-mode operation with the output taken at pin 6. |
| 5 | TRIM | passive | Trim node for initial error nulling, with a 36 V absolute maximum to ground; a 25 kΩ potentiometer between VOUT, TRIM and GND gives a coarse 4% adjustment range. |
| 6 | VOUT | output | Reference output at 2.5 V or 3.0 V that can source or sink up to 10 mA and is safe for indefinite short to ground and momentary short to VIN. |
| 7 | NC | unconnected | Internally tied through a 20 kΩ resistor to +VIN and used only for production test, so it should be left unconnected and not used as the LT1019 self-heater pin without accounting for the added load. |
| 8 | O/P SELECT | input | Output voltage select: leave unconnected for a 2.5 V output or connect to GND for a 3.0 V output. |
