Integrated Circuit
5–Point LED VU Scale Bar Level Meter Driver
Description:
The NTE1866 is a monolithic integrated circuit in a 9–Lead SIP type package designed for use as an
LED level meter driver for radio cassette recorders and other audio products.
Features;
D Rectifying amplifiers are used to allow operation by AC or DC input.
D The wide display range covers –13dB to +17dB, enabling the display of even signals with wide
dynamic range.
D The drive current for the LEDs is regulated, eliminating LED current variations with supply volt-
age variations.
D The reference voltage is built in to eliminate output display variations with variations of supply
voltage.
D Wide supply voltage range (3.5V to 16V) enables a wide range of applications.
Applications:
D VU meters
D Signal meters
D Other display devices
