Description
The CXA1598M/S is a bipolar IC developed for recording equalizer amplifier in analog cassette decks. Incorporating the filter circuit has eliminated the external inductor. Also, each of the six parameters required for equalizer amplifiers can be set independently with external resistance.

Features
• Inductor (coil) is unnecessary
• The six parameters (low frequency gain, medium frequency gain, peaking gain, medium frequency
compensation frequency, peaking frequency, and Q) required for recording equalizer amplifiers can be set independently with external resistance
• 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)
• Built-in 2 channels
• Small package

Applications
Recording equalizer amplifier for stereo analog
cassette decks
