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. HADKH55-series heads)
