AD780ANZ
Analog Devices · Voltage Reference · PDIP-8
AD780ANZ from Analog Devices, in a PDIP-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 | DNC | unconnected | Do not connect; this pin must be left unconnected (DNC = do not connect to this pin). |
| 2 | +VIN | power_in | Supply input; the AD780 operates from 4.0 V to 36 V, with +VIN to ground rated at 36 V maximum. |
| 3 | TEMP | output | Temperature output that is about 560 mV at 25°C and rises about 2 mV/°C; it is rated 36 V maximum to ground and its current draw strongly affects VOUT, so it must be buffered by a suitable op amp. |
| 4 | GND | power_in | Ground reference pin for the device. |
| 5 | TRIM | passive | Output trim connection for a coarse trim (4% range) potentiometer between VOUT, TRIM and GND or fine trim through a large series resistor; TRIM to ground is rated 36 V maximum. |
| 6 | VOUT | output | Precision 2.5 V or 3.0 V reference output that can source or sink up to 10 mA and is safe for indefinite short to ground and momentary short to VIN. |
| 7 | DNC | unconnected | Do not connect; internally this pin is a 20 kΩ resistor to +VIN used only for production test, so it must not be tied to any external circuit. |
| 8 | 2.5V/3.0V O/P SELECT | input | Output voltage select: leave unconnected (DNC) for 2.5 V output or connect to GND for 3.0 V output. |
