Ordering number:ENN1410B
Monolithic Digital IC
LB1403N Series
5-Dot Red/Green LED Level Meter
Use
• AC level meters such as VU meters.
• DC level meters such as signal meters.
Features and Functions
• Capable of generating a bar-display for input
voltage with 5 LEDs.
• Operates from either AC or DC input
voltage because of on-chip rectifier amplifier.
• Lighting levels remain stable to line regulation because of on-chip
voltage reference.
• LEDs are driven by a constant current ; stable to line regulation.
• Power supply
voltage range is wide (3.
5 to 16V), for a wide range of applications.
• Five types of ICs constitute the series with various lighting levels of the LEDs and driving curren...
