TEXAS INSTRUMENTS LM3915N-1/NOPB 发光二极管驱动器, 10输出, 共阳极, 3V-25V输入, 1.28V/30mA输出, DIP-18
The is a monolithic IC that senses analogue voltage levels and drives ten LEDs, LCDs or vacuum fluorescent displays, providing a logarithmic 3dB/step analogue display. One pin changes the display from a bar graph to a moving dot display. LED current drive is regulated and programmable, eliminating the need for current limiting resistors. The whole display system can operate from a single supply as low as 3V or as high as 25V. The IC contains an adjustable voltage reference and an accurate ten-step voltage divider. The high-impedance input buffer accepts signals down to ground and up to within 1.5V of the positive supply. Further, it needs no protection against inputs of ±35V. The input buffer drives 10 individual comparators referenced to the precision divider. Accuracy is typically better than 1db.
Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
