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 volt age 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
