Dual Element Detectors

TO-39 / TO-5 housing Competitive cost version Designed for motion control The LHi 874 and LHi 878 pyroelectric infrared-detector series are the standard dual element design recommended for all variants of motion control. They include a dual element pyro-electric ceramic with FET in source

5V/3.3V/3V/Adjustable-Output, Step-Up/Step-Down DC-DC Converters

General Description The MAX877/MAX878/MAX879 are pulse-skipping, step-up/step-down DC-DC converters that provide a regulated output from inputs both above and below the output. They require only three external components—an inductor (typically 22µH) and two filter capacitors. Features ♦ Regulat
