AN6291 Datasheet, PDF (1/7 Pages) Panasonic Semiconductor – Dual dbx II Noise Reduction System ICs

ICs for Cassette, Cassette Deck
AN6291, AN6291S
Dual dbx II Noise Reduction System ICs
s Overview
The AN6291 and the AN6291S are the single chip ICs
suitably developed for noise reduction of dbxII type and
used for stereo operation. They can be used for U.S.
sound multiplex TV. 1.8V low voltage operation enables
to apply for battery-operated equipment to the Hi-Fi deck.
Package is available for 22-pin DIL plastic and 22-pin
SOP package. Equipment can be minitualized and high
integration.
s Features
• Wide dynamic range : 110dB
• Low operating voltage : V_{CC (min.)} =1.8V
• Fewer external components
• Adjustment : only one
• Low power consumption
• Wide operating supply voltage range :
V_{CC (opr)} =1.8V to 14V
