Description
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 currents.
SIP-9 pin package and fewer externally connected components resuit in smaller space requirements on the circuit board.
Low noise at LED lighted mode.
