ADR440ARMZ-REEL7

Analog Devices · Voltage Reference · MSOP-8

ADR440ARMZ-REEL7 from Analog Devices, in a MSOP-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; no circuit should be connected to this pin.
2 VIN power_in Input voltage connection, specified for 3 V to 18 V with at least 500 mV headroom above VOUT.
3 NIC unconnected Internally not connected; these pins are not internally interconnected to the rest of the device.
4 GND power_in Ground reference for the device.
5 TRIM passive Output voltage trim pin; a potentiometer between VOUT and GND with its wiper here trims the output within 0.5% without affecting performance, and all trim resistors must be low-temperature-coefficient types.
6 VOUT power_out Output voltage; sources up to 10 mA and sinks up to -5 mA, with output short-circuit current of 27 mA.
7 NIC unconnected Internally not connected; these pins are not internally interconnected to the rest of the device.
8 DNC unconnected Do not connect; no circuit should be connected to this pin.
