٨Description
BD37531FV, BD37532FV, BD37533FV, BD37534FV are sound processors built-in 3-band equalizer for car audio. The
functions are stereo input selector available to switch single end input and ground isolation input, input-gain control, main
volume, loudness, 5ch fader volume, LPF for subwoofer(except BD37531FV), mixing input(except BD37531FV,
BD37532FV). Moreover, “Advanced switch circuit”, that is ROHM original technology, can reduce various switching noise
(ex. No-signal, low frequency likes 20Hz & large signal inputs). “Advanced switch” makes control of microcomputer easier,
and can construct high quality car audio system.
٨Features
1) Reduce switching noise of input gain control, mute, main volume, fader volume, bass, middle, treble, loudness
by using advanced switch circuit [Possible to control all steps]
2) Built-in differential input selector that can make various combination of single-ended / differential input.
3) Built-in ground isolation amplifier inputs, ideal for external stereo input.
4) Built-in input gain controller reduces switching noise for volume of a portable audio input.
5) Decrease the number of external components by built-in 3-band equalizer filter, LPF for subwoofer (except BD37531FV),
2
loudness filter. And, possible to control Q, Gv, fo of 3-band equalizer and fc of LPF, Gv of loudness by I C BUS control
freely
6) It is possible for the bass, middle, treble to the gain adjustment quantity of ±20dB and 1 dB step gain adjustment.
7) Terminals for the subwoofer outputs are equipped, and the audio signal outputs of front, back and subwoofer can be
chosen with the I2C BUS control.
8) Built-in mixing input, mixing attenuator. (except BD37531FV, BD37532FV)
9) Bi-CMOS process is suitable for the design of low current and low energy. And it provides more quality for small
scale regulator and heat in a set.
10) Package is SSOP-B28. Putting input-terminals together and output-terminals together can make PCB layout easier and
can makes area of PCB smaller.
2
11) It is possible to control by 3.3V / 5V for I C BUS.
٨Applications
It is the optimal for the car audio. Besides, it is possible to use for the audio equipment of mini Compo, micro Compo, TV
etc with all kinds.

All values referred to VIH min. and VIL max. Levels (see Table 2).
* A device must internally provide a hold time of at least 300 ns for the SDA signal (referred to the VIH min. of the SCL
signal) in order to bridge the undefined region of the falling edge of SCL.
About 7(tHD;DAT), 8(tSU;DAT), make it the setup which a margin is fully in .

٨Thermal Derating Curve
About the thermal design by the IC
Characteristics of an IC have a great deal to do with the temperature at which it is used, and exceeding absolute
maximum ratings may degrade and destroy elements. Careful consideration must be given to the heat of the IC from the
two standpoints of immediate damage and long-term reliability of operation.
