Description:
The NTE1633 is a complete TV sound channel in a 20–Lead DIP type package with DC tone and vol-
ume controls plus separate VCR input and output connections. Supplied in a 20–pin DIP, the device
delivers an output power of 4W into 16
(d = 10%, V
S
= 24V) or 1.5W into 8
(d = 10%, V
S
= 12V).
Included in the NTE1633 are: IF amplifier limiter, active low–pass filter, AF preamplifier and power
amplifier, turnoff muting, mute circuit and thermal protection.
High output, high sensitivity, excellent AM rejection and low distortion make the device suitable for
use in TVs of almost any type. Further, no screening is necessary because the device is free of radi-
ation problems.
