NTE1866
Integrated Circuit
5鈥揚(yáng)oint LED VU Scale Bar Level Meter Driver
Description:
The NTE1866 is a monolithic integrated circuit in a 9鈥揕ead 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 鈥?3dB 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
