The CA1004 is a two-terminal, temperature compensated,

micropower band-gap voltage reference, which provides a

fixed voltage for a wide range of input currents (10µA to

20mA). The high stability of the device is primarily the result

of the low temperature coefficient Thin Film Resistor process

and the tight output voltage tolerance is obtained by resistor

Laser trimming at the wafer level. This gives the benefit of

eliminating the need of external voltage adjustment.
