Sound Processors for BOOM BOX / Mini-component Stereo Sound Processors with Built-in 3-band Equalizers BD3403FV, BD3861FS, BD3883FS ● 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 BD3403FV BD3861FS BD3883FS Operating Voltage Range 6.5 to 9.5V 6.5 to 9.5V 6.5 to 9.5V Equalizer 3 band (BASS, MIDDLE, TREBLE) 3 band (BASS, MIDDLE, TREBLE) 3 band (BASS, MIDDLE, TREBLE) Front Volume 0 to -30dB/2dB step 0 to -50dB/2dB step -50 to -70dB/4dB step, -∞dB 0 to -87dB/1dB step, - ∞ dB Rear Volume 0 to -59dB/1dB step, -∞dB 0 to -59dB/1dB step, -∞dB 0, -10dB Input Gain 0 to 26dB/2dB step 0 to 26dB/2dB step 0, 6, 12, 16, 20, 23, 26, 29dB Microphone Input ○ ○ Surround ○ ○ Package SSOP-B40 SSOP-A32 SSOP-A32 ● Absolute maximum ratings (Ta=25℃) Prameter Symbol Ratings Unit BD3403FV BD3861FS,BD3883FS Power Supply Voltage Vcc 10 10 V Power Dissipation Pd 900 *1 950 *2 mW Input Voltage Range Vin GND-0.3 to VCC+0.3 GND-0.3 to VCC+0.3 V Operating Temperature Range Topr -25 to +75 -25 to +75 ℃ Storage Temperature Range Tstg -55 to +125 -55 to +125 ℃ *1 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 Symbol Ratings Unit BD3403FV Vcc 6.5 to 9.5 V BD3861FS BD3883FS No.10086EAT01 |
