Notes on Operation
1. Power supply
The CXA1598 is designed basically for positive/negative dual power supplies, and can also operate with a
single power supply. Connect the power supplies for each case as shown below:
Pin Nos. in parentheses are those for the CXA1598S.
For a single power supply, connect a decoupling capacitor (10μF or more) to the GND (VG) pin. The ripple
rejection ratio depends on the capacitance of this capacitor.
2. Low frequency boost
The CXA1598 can implement low frequency boost simply by connecting a capacitor to the BOOST pins.
Although the boost is fixed to 6dB, the time constant which determines the cut-off frequency can be set to
any desired value depending on the external capacitor. The pole (f

) and zero (f

) shown in Fig. 3. Low
frequency boost frequency response can be expressed, with the external capacitor assumed to be C

When not using low frequency boost, follow the procedure described below.
For positive/negative dual power supplies
Connect the BOOST pins to GND.
For single power supply
Connect a fairly large capacitor (3.3μF or more) to the BOOST pins or simply leave the BOOST pins open. If
the BOOST pins are left open, note that the output level increases by 6dB, so the input level should be set
6dB down. The CXA1598 is basically designed for positive/negative dual power supplies and the BOOST
pins cannot be easily connected to GND as in the case of positive/negative dual power supplies.
3. Resistance connected to the IREF pin as well as the GL, GH, GP, fM, f/Q, and fxQ pins
The recording equalizer amplifier frequency response is determined by the resistance connected to the IREF
pin as well as the GL, GH, GP, fM, f/Q, and fxQ pins. This means that the accuracy of the recording equalizer
amplifier frequency response is determined by the resistance connected to these pins. Therefore, the
resistors used for this purpose must be free of unevenness and have excellent temperature characteristics
(e.g., a metallic film resistor).
