Micropower Voltage Reference CA1004
FEATURES
- • Very Tight Initial Voltage Tolerance
- • Very Low Operating Current PRODUCT DESCRIPTION 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.
