CXA1498S Overview
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.
CXA1498S Key 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)
