Part number : B1403N, LB1403N
Functions : 5-Dot Red/Green LED Level Meter
Package information : ZIP 9 Pin
Manufacturer : Sanyo Electric
Features and Fuctions
1. Capable of generating a bar-display for input voltage with 5 LEDs.
2. Operates from either AC or DC input voltage because of on-chip rectifier amplifer.
3. Lighting levels remain stable to line regulation because of on-chip voltage reference.
4. LEDs are driven by a contant curret; stable to line regulation.
5. Five types of ICs constitute the series with various lighting levels of the LEDs and driving currents.
1. AC level meters such as VU meters
2. DC level meters such as signal meters
