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;
● Rectifying amplifiers are used to allow operation by AC or DC input.
● The wide display range covers –13dB to +17dB, enabling the display of even signals with wide dynamic range.
● The drive current for the LEDs is regulated, eliminating LED current variations with supply voltage variations.
● The reference voltage is built in to eliminate output display variations with variations of supply voltage.
● Wide supply voltage range (3.5V to 16V) enables a wide range of applications.

Applications:
● VU meters
● Signal meters
● Other display devices
