CXA1598M/S
Description of Operation
1. Recording equalizer amplifier
The primary features of the CXA1598 recording equalizer amplifier are that by taking full advantage of
monolithic filter technology, an LC resonance circuit consisting of a coil and capacitor normally required for
high frequency compensation is dispensed with and medium and low frequency sensitivity compensation is
performed with its internal filter alone. In addition, 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 as desired simply by attaching resistors to the GL, GH, GP, fM, f/Q,
and fxQ pins.
This IC has the circuit configuration shown in Fig. 1 to provide the optimum frequency response required for
recording equalizer amplifiers.

2. Low frequency boost
The CXA1598 implements low frequency boost simply by attaching an external capacitor to the BOOST pins.
Signals are boosted by approximately 6dB. The boost cut-off frequency can be freely set with the value of the
external capacitor.
