Description
Introduction to LTC1421CG-2.5: It is a precision 2.5 V voltage reference IC from Linear Technology (now Analog Devices). The “2.5” denotes the output reference voltage, and “CG” indicates the particular packaging/grade variant. The device provides a stable, low-noise reference for ADCs/DACs and other precision analog front-ends. Key advantages typically include tight initial accuracy, low temperature drift, and modest quiescent current in a compact package. Common applications are precision instrumentation, data acquisition, portable/battery-powered instruments, and any circuit needing a reliable reference voltage. For exact specifications—voltage accuracy, temperature coefficient, noise density, load and line regulation, and quiescent current—consult the LTC1421CG-2.5 datasheet and related application notes.
