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/HIGH

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)
