Voltage Reference – Applications

Automotive

Wide variety of automotive shunt and series references spanning across multiple output voltage levels and initial accuracy grades. Series voltage reference families with additional features such as enable/shutdown Iq pin and noise reduction/TRIM pin address low power consumption and high accuracy demands, while fixed and adjustable shunt voltage references solve wide Vin needs.
