Description

The CXA1498S/M is a bipolar IC designed as equalizer amplifier for tape redorder recording/playback. This IC is particularly well-suited for double cassette deck applications. An on-chip filter serves to greatly reduce the number of external parts.

Features

? Recording equalizer amplifier × 2

(Monolithic filter eliminates the need for external resonance circuit)

? AGC (automatic gain control) × 2

? Playback equalizer amplifier × 2

(Variable resistor eliminates the need for external feedback resistor)

? Electronic switch for playback head (Changes between A and B decks)

? Electronic switch for tape equalization (120μs/70μs) (Independently for A and B decks)

? Electronic switch for metal tapes

? Electronic switch for normal/high speed dubbing (Effective for both REC EQ and PB EQ)

? Recording mute function (Soft mute is possible through use of an external time constant circuit)

? DC controllable for fade IN/OUT (Controls recording mute function)

? Playback mixing output pin provided (For tune selection)

? Use of this IC simplifies the construction of double cassette dubbing system

Applications

Recording/playback equalizer amplifier, playback mixing amplifier and AGC for analog stereo tape recorders
