NTE998
Integrated Circuit
1.22V Reference Diode
Description:
The NTE998 is a temperature compensated low voltage reference device in a TO92 type package.
A single monolithic structure is obtained by utilizing transistors and thin film resistors. Benefits of this
construction is low noise, low current, and good long term stability associated with modern integrated
circuits.
These characteristics make this device ideal for applications in battery operated equipment or where
low power is necessary.
