- Guaranteed 1% Initial Voltage Tolerance
- Guaranteed 1 Ohms Dynamic Impedance
- Very Low Power Consumption
Typical Application
Description
The H (Metal Can), J (Ceramic), and K (Metal Can) Packages From Linear Technology Are Now Obsolete
The LM185-2.5 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 operation specifications at currents as low as 20mA. The nominal voltage is 2.5V with both 1% and 2% tolerances available. Some additional features are: maximum dynamic impedance of 1W, low noise and excellent stability over time and temperature. The advanced design, processing and testing techniques make Linear’s LM185-2.5 a superior choice over previous designs. A circuit for cold junction compensation of a thermocouple is shown below.
For applications requiring guaranteed temperature drift, see the LT1034 data sheet.
