Ordering number: EN 1410B Monolithic Digital IC No. 14108 LB1403N.Series SANYO | 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 appli- cations. . Five types of ICs constitute the series with various lighting levels of the LEDs and driving currents. .« SEP-9 pin package and fewer externally connected components result in smaller space requirements on the circuit board. + Low noise at LED lighted mode LB1403N Series [type Wo.

When the C1, Ry time constant is smaller: «eeeeee The response time (attack time and release time) is made faster. . Considerations relative to Pd max of the package: Due to the constant current. ILgp» most of the power consumed by the circuits is consumed within the IC. When lighting the five LEDs continuously for a prolonged length of time, make sure that Vo, does not exceed: LB1403N, 1413N, {43N Vec=9V LB1423N, 1433N Vo =14V When using a higher power supsly voltage, insert a resistor in series with the LEDs to restrain the power consumed within the IC package.
