Introduce this Module:
The LM3915 is a monolithic IC Chip that senses analog voltage levels and drives ten LEDs, LCDs or vacuum fluorescent displays, providing a logarithmic 3 dB/step analog display. One pin change the display from a bar graph to a moving dot display. Light-Emitting Diode 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 3 Voltage or as high as 25V.
Some Core Parameters:
SPECIAL FEATURES :
● 3dB/step, 30dB Range
● Drives LEDs, LCDs, or Vacuum Fluorescents
● Bar or Dot Display Mode Externally IC Chip Selectable by User
● Expandable to Displays of 90dB
● Internal Voltage Reference from 1.2Volt to 12Volt
● Operates with Single Power Supply of 3Volt to 25Volt
● Inputs Operate Down to Ground
● Output Current Programmable from 1milliampere to 30milliampere
● Outputs are Current Regulated, Open Collectors
● Directly Drives TTL or CMOS
