Samples are now available for a number of models of the new ADL-Series Giant Magnetoresistive (GMR) Digital Switches. The new devices are NVE’s smallest packaged parts at just 1.1 mm x 1.1 mm x 0.45 mm, and are ideal for ultraminiature industrial controls.

	ADL-Series Sensors fit
	on the head of a pin.

The output is configured as a magnetic “switch,” where the output turns on when a magnetic field is applied and off when the field is removed. The field can be either polarity, and the magnetic operate point is extremely stable over supply voltage and temperature.

Internally duty cycled versions (the ADL0xx and ADL1xx Series) reduce power consumption. An integrated latch ensures the output is available continuously. Two duty-cycle frequencies are available, offering a tradeoff between update frequency and power consumption. A continuously-operating version (the ADL9xx Series) is also available.

Continuously-operating versions consume less than a milliwatt, while duty-cycled versions consume less than a microwatt.

ADL-Series parts are ideal for battery-powered devices such as gas and water meters, portable instruments, or anyplace where extremely low power is required.

Key specifications are:
  •  1.1 mm x 1.1 mm x 0.45 mm ULLGA package
  •  2.4 - 3.6 V supply voltage
  •  As low as 72 nW typ. power consumption at 2.4 V
  •  20, 28, or 40 Oersted operate points
  •  Current-sinking output up to 100 µA
  •  -40°C to +125°C temperature range

Samples are available to qualified customers.
