ADR3430ARJZ-R7

Analog Devices · Voltage Reference · SOT-23-6

ADR3430ARJZ-R7 from Analog Devices, in a SOT-23-6. 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 FORCE power_in Ground drive connection that carries the load return current; it can be tied directly to GND SENSE when IR drop is negligible, and the Kelvin arrangement otherwise lets the internal amplifier correct for drops in the ground path.
2 GND SENSE power_in Ground voltage sense connection that must be connected directly to the lowest-potential point in the application.
3 ENABLE input Enable connection that turns the device on or off: driving it to 0.85 × VIN or higher enables the reference, driving it to 0.7 V or lower puts it in low-power shutdown (supply current below 5 µA), and it should not be held between 0.7 V and 0.85 × VIN; tie it to VIN if shutdown is not used.
4 VIN power_in Input voltage connection; for the ADR3430 the specified input range is 3.2 V to 5.5 V, the absolute maximum supply is 6 V, and VIN must rise and fall at a minimum slew rate of 0.1 V/ms.
5 VOUT SENSE passive Output voltage sense connection that must be connected directly to the voltage input of the load device to maintain maximum output accuracy.
6 VOUT FORCE power_out Voltage reference output (3.000 V nominal for the ADR3430) that can source up to 10 mA and sink up to −3 mA, with the output capacitor placed as close to this pin as possible.
