BD3883FS

Sound Processors for BOOM BOX / Mini-component Stereo Sound Processors with Built-in 3-band Equalizers BD3403FV, BD3861FS, BD3883FS No.10086EAT01 ●Description The Sound Processor has a built-in 3 Band Equalizer and can be controlled with a 2-wire serial. It is suited for a sound quality design which incorporates various functions, ranging from source selectors, such as BOOM BOX, Mini-audio systems and Micro-audio systems to preamplifiers at the front stage of the power amp. ●Features 1) High S/N, achieved by implementing 2-stage configuration of Front Volume and Rear Volume. 2) Provides surround and rear volume with Soft-switch to reduce a shock sound during switching functions(BD3883FS). 3) Volume and tone implemented with the resistance ladder circuit (to achieve high performance with low noise and low distortion). 4) Uses the BiCMOS process that achieves low-consumption current, which contributes to an energy-saving design. Using the BiCMOS process, has the advantage in quality over the scaling down of the internal regulators and heat controls. 5) SSOP-A32 and SSOP-B40 are used for the packages. Input pins and output pins are organized and separately laid out so as to keep the signal flows in one direction which consequently, simplify pattern layout of the set board and decrease the board dimensions. ●Applications BOOM BOX, mini-audio systems, and micro-audio systems. ●Product lineup Parameter Operating Voltage Range Equalizer Front Volume Rear Volume Input Gain Microphone Input Surround Package ●Absolute maximum ratings (Ta=25℃) Prameter Power Supply Voltage Power Dissipation Input Voltage Range Operating Temperature Range Storage Temperature Range *1 BD3403FV BD3861FS BD3883FS 6.5 to 9.5V 6.5 to 9.5V 6.5 to 9.5V 3 band 3 band 3 band (BASS, MIDDLE, TREBLE) (BASS, MIDDLE, TREBLE) (BASS, MIDDLE, TREBLE) 0 to -50dB/2dB step 0 to -30dB/2dB step 0 to -87dB/1dB step, -∞dB -50 to -70dB/4dB step, -∞dB 0 to -59dB/1dB step, -∞dB 0 to -59dB/1dB step, -∞dB 0, -10dB 0 to 26dB/2dB step ○ ○ SSOP-B40 0 to 26dB/2dB step ○  SSOP-A32 0, 6, 12, 16, 20, 23, 26, 29dB  ○ SSOP-A32 Symbol Vcc Pd Vin Topr Tstg Ratings BD3403FV 10 900*1 GND-0.3 to VCC+0.3 -25 to +75 -55 to +125 BD3861FS,BD3883FS 10 950*2 GND-0.3 to VCC+0.3 -25 to +75 -55 to +125 Unit V mW V ℃ ℃ Reduced by 9.0 mW/℃ over 25℃, when installed on the standard board (size: 70×70×1.6mm) for (BD3403FV). *2 Reduced by 9.5 mW/℃ over 25℃, when installed on the standard board (size:70×70×1.6mm) for (BD3861FS,BD3883FS). ●Operating voltage range Prameter BD3403FV BD3861FS BD3883FS Symbol Vcc Ratings 6.5 to 9.5 Unit V www.rohm.com © 2010 ROHM Co., Ltd.

All rights reserved. 12/15 2010.10 - Rev.A BD3403FV,BD3861FS,BD3883FS Technical Note ●Notes for use 1) Numbers and data in entries are representative design values and are not guaranteed values of the items. 2) Although ROHM is confident that the example application circuit reflects the best possible recommendations, be sure to verify circuit characteristics for your particular application. Modification of constants for other externally connected circuits may cause variations in both static and transient characteristics for external components as well as this Rohm IC. Allow for sufficient margins when determining circuit constants. 3) Absolute maximum ratings Use of the IC in excess of absolute maximum ratings, such as the applied voltage or operating temperature range (Topr), may result in IC damage. Assumptions should not be made regarding the state of the IC (short mode or open mode) when such damage is suffered. A physical safety measure, such as a fuse, should be implemented when using the IC at times where the absolute maximum ratings may be exceeded. 4) GND potential Ensure a minimum GND pin potential in all operating conditions. Make sure that no pins are at a voltage below the GND at any time, regardless of whether it is a transient signal or not. 5) Thermal design Perform thermal design, in which there are adequate margins, by taking into account the permissible dissipation (Pd) in actual states of use. 6) Short circuit between terminals and erroneous mounting Pay attention to the assembly direction of the ICs. Wrong mounting direction or shorts between terminals, GND, or other components on the circuits, can damage the IC. 7) Operation in strong electromagnetic field Using the ICs in a strong electromagnetic field can cause operation malfunction. 8) 2-wire serial control Because SC and SI terminals are designed for inputting high-frequency digital signals, wiring and layout patterns should be routed as not to cause interference with the analog-signal-related lines. 9) E Input external resistance (BD3883FS) To avoid a sudden noise into E Input, external resistance (4.7kΩ) should be connected as close as possible to the IC terminal. 10) Function switching Action to absorb shock sounds is taken when switching between the Volume, Treble, Middle and Bass functions. 11) Power-ON Reset (BD3883FS) A built-in circuit for performing initialization inside the IC at Power-ON is provided. Specifically, the initial states are set as described in the table below. In the case of the setting design, however, to be on the safe side, it is recommended that data shall be sent to all the addresses as initial data at power-ON and, until this sending operation is completed, MUTE shall be applied. To avoid malfunctions, serial data signals must be set to the Low state at power-ON/OFF. Function Input Selector Input Gain RECOUT Volume Surround Treble Middle Bass Rear Volume Initial State MUTE 0 dB OFF ∞dB OFF 0 dB 0 dB 0 dB 0dB 12) Step switching noise (BD3883FS) For Surround and Rear Volume, an external capacitor C is attached to the CAP pin to control the switching step noise. In the application circuit, a constant value, as an example, is shown by the CAP pin. The time constant for charge/discharge of the capacitor C (varying between VBE to 5VBE (2.65V)) controls the slow switching operation. The switching time constant T is calculated as the follows: 5 T=2.55×10 ×C VBE has temperature characteristics and may affect the value of the time constant T. www.rohm.com © 2010 ROHM Co., Ltd.

Therefore, it is recommended to implement the MUTE function. MUTE setting example MUTE SERIAL DATA SERIAL DATA L=ON H=OFF 40～60ms INPUT SOURCE SWITCHING Fig.17 14) Constraints of serial control (BD3883FS) On Soft-switching of the RECOUT, Surround, and Rear Volume functions, data must not be sent serially to the functions before the switching operation is completed. If the function for Soft-switch should serially send the data (Data(4)) on the same Select Address, the time interval between the send operations must be set to 500 -600msec. Direction Data(4) Data(4) T Fig.18 15) Function setting while muting Volume (BD3883FS) While muting Volume, to avoid increasing residual noise, set Bass, Middle and Treble to 0dB, Surround to OFF, and Rear Volume to -10dB. www.rohm.com © 2010 ROHM Co., Ltd.
