CXA1597M

CXA1597M/P Recording Equalizer Amplifier for Stereo Cassette Decks 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.
