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)

Recording equalizer amplifier
Recording reference output level
NORM-NORM mode
Recording equalizer amplifier reference output
level (315Hz) (This output level is the tape
reference 0dB which generates magnetic flux of
250nWb/m)
All of the recording equalizer amplifier blocks use
this level as their reference level.

CXA1597M/P
Also, the relationship of time constants fM, fP and Q is configured by the product of the current obtained with
the "voltage → current converter circuits" and the IC's internal capacitance connected to the output of each
"multiplier circuit". By using the currents determined by the CXA1597 external resistance which are not
dependent on the internal resistance for control, the coefficients for voltage → current conversion become
certain ratios to the internal resistance; therefore, the frequency response does not depend on the internal
resistance.

2. Low frequency boost
The CXA1597 implements low frequency boost simply by attaching an external capacitor. As shown in Fig. 1,
this IC contains a resistance-based attenuation circuit after the input amplifier, with one of the resistors
connected to the BOOST pins (Pins 6 and 11). When a capacitor is connected to these BOOST pins (Pins 6
and 11), the following transfer function is obtained.
GBOOST (s) =
s • C1 • R7 • R8 + R7
(s = jω)
s • C1 • (R4 • R7 + R7 • R8 + R8 • R4) + (R4 + R7)
From the above, items f1, f2, A1, and A2 in Fig. 3 are transformed into the following:
f1 =
R4 + R7
2π • C1 • (R4 • R7 + R7 • R8 + R8 • R4)
