Description
The CXA1597M/P is a bipolar IC developed for recording equalizer amplifier in analog cassette decks. It is suited specifically for double cassette decks. Incorporating the filter circuit greatly reduces the external parts.

Features
• Built-in filter required for recording equalizer amplifiers
• Inductor (coil) is unnecessary
• Low frequency boost is possible with an external capacitor
• Built-in recording mute function (requiring only an external time constant circuit to implement soft mute)
• Fade in/out DC controllable
• NORM/CrO2/METAL tape mode switching function
• NORM/HIGH tape speed recording switching function
• DC controllable for recording level calibration (approximately ±6dB variable)
• DC controllable for high frequency equalizer amplifier gain (approximately ±4dB variable)
• Built-in 2 channels
• Small package

Applications
    Recording equalizer amplifier for stereo analog cassette decks (Supports ALPS ELECTRIC CO., LTD. HADKH55-series heads)
