Description
The LM185-1.2 is a two terminal band gap reference diode that has been designed for applications which require precision performance with micropower operation. The device provides guaranteed operating specifications at currents as low as 10µA. The nominal voltage is 1.235V with both 1% and 2% tolerances available. Some additional features are: maximum dynamic impedance of 1 Ohm, low noise and excellent stability over time and temperature. Advanced design, processing and testing techniques make Linear’s LM185-1.2 a superior choice over previous designs. A micropower 5V reference application is shown below. For guaranteed TC, micropower references, see the LT1034 data sheet.
Linear Technology offers many demo boards free of charge to qualified customers. Contact your local sales office or distributor to inquire about a demo board. Certain demo boards are also available for sale via credit card on this website. Demo boards are for evaluation purposes only. It remains the customer’s responsibility to verify proper and reliable operation in the actual end application.
