Description

The LM3915N-1/NOPB 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.

Features:

  • 3dB/Step, 30dB Range
  • Drives LEDs, LCDs or Vacuum Fluorescents
  • Bar or Dot Display Mode Externally Selectable by User
  • Expandable to Displays of 90dB
  • Internal Voltage Reference from 1.2 to 12V
  • Inputs Operate Down to Ground
  • Output Current Programmable from 1 to 30mA
  • Input Withstands ±35V without Damage or False Outputs
  • Outputs are Current Regulated, Open Collectors
  • Directly Drives TTL or CMOS
  • Internal 10-step Divider is Floating and can be Referenced to a Wide Range of Voltages
  • Green Product, No Sb/Br

Applications:

  • Power Management
  • LED Lighting

Warnings

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.
