Features and Functions
鈥?Capable of generating a bar-display for input voltage with
5 LEDs.
鈥?Operates from either AC or DC input voltage because of
on-chip rectifier amplifier.
鈥?Lighting levels remain stable to line regulation because
of on-chip voltage reference.
鈥?LEDs are driven by a constant current ; stable to line regu-
lation.
鈥?Power supply voltage range is wide (3.5 to 16V), for a
wide range of applications.
鈥?Five types of ICs constitute the series with various light-
ing levels of the LEDs and driving currents.
鈥?SIP-9 pin package and fewer externally connected com-
ponents resuit in smaller space requirements on the cir-
cuit board.
鈥?Low noise at LED lighted mode.
