Part number lm3914n-1
BRAND National Semiconductor [NS]
Packaging dip-18
Date code 10+
Price 0.5~0.6usd
Summary monolithic integrated circuit, DIP-18, 1365 mW, 25V, 2 mA to 30 mA
Description as follow:
The LM3914N-1 is a monolithic integrated circuit that senses analog voltage levels and drives 10 LEDs, providing a linear analog display. A single pin of LM3914N-1 changes the display from a moving dot to a bar graph. Current drive to the LEDs is regulated and programmable, eliminating the need for resistors. This feature is one that allows operation of the whole system from less than 3V.
