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.

·C1, R1 time constant :
The response time can be varied by varying the C1, R1 time constant (mainly the C1 value).
When the C1, R1 time constant is larger :
..................The response time (attack time and release time) is made slower.
When the C1, R1 time constant is smaller :
..................The response time (attack time and release time) is made faster.
· Considerations relative to Pd max of the package :
Due to the constant current I
When lighting the five LEDs continuously for a prolonged length of time, make sure that VCC does not exceed :
LB1403N, 1413N, 1443N VCC=9V
LB1423N, 1433N VCC=14V
When using a higher power supply voltage, insert a resistor in series with the LEDs to restrain the power consumed
within the IC package.
For LB1403N, 1413N, 1443N :
, most of the power consumed by the circuits is consumed within the IC.
