CXA1599Q

CXA1599Q 1-chip Cassette Deck For the availability of this product, please contact the sales office. Description The CXA1599Q is an IC for audio cassette decks. All analog signal processing functions, except Dolby NR, are incorporated in a single chip. As a result, a double cassette deck system can be simply configured by adding a Dolby IC. Features • Electronic recording volume for setting recording level (with a balance volume) • Recording equalizer amplifier (with calibration and low frequency boost functions) • Recording mute function (soft mute and fader possible) • Playback head amplifier switch function (deck A/B switch) • NR pass amplifier (NR IN/PASS switch) • Headphone amplifier with electronic volume • Full-wave rectifier output amplifier for level meter (with time constant function) • HPF amplifier for AMS (with BS/AMS gain switch function) • Electronic switch for tape EQ selection (120µs/70µs) • Electronic switch for metal tape selection • Electronic switch for normal/double speed dubbing selection (only for recording equalizer) • Line mute function • Double cassette dubbing system can be easily configured with this single IC. 48 pin QFP (Plastic) Applications Analog signal processing (except Dolby NR) for stereo analog cassette deck (ALPS ELECTRIC CO., LTD.
