Rohm BD3816K1 6.1ch sound processor Datasheet

Sound Processors for Home Theater Systems
6.1ch
Sound Processor
BD3816K1,BD3817KS
No.10081EAT06
●Description
The BD3816K1 and BD3817KS are 6.1ch sound processors. Functions required for applications, such as AV receivers and
home theater systems, are integrated into a single chip. A wide dynamic range of 132dB is achieved by utilizing the
BiCMOS process.
●Features
1) Dynamic range: 132dB (Volume Direct Mode, VOL=MUTE, IHF-A)
2) Independent 7 channels for Master Volume (0 to -95 dB, MUTE 1dB/Step)
nd
nd
3) Supporting 2 room entertainment/2 source recording.
4) Low current consumption design achieved by adopting the Bi-CMOS process.
5) Maximum output voltage: 4.2Vrms (VCC=7V, VEE=-7V, RL=10k).
6) Built-in Input Gain Amp useful for amplifying input signals (0-7dB, 1dB/Step).
7) Built-in Output Gain Amp useful for adjusting output signal voltages (0-17dB, 1dB/Step)
8) Built-in mixing circuit for distributing the output signals from Center and Subwoofer channel to Front R/L channels
(0, -3, -4.5dB).
9) 2ch Volume control BD3812F or 6ch Function Switch BD3843FS can be controlled simultaneously
by the serial control bus.
10) REC A output terminal with a REC input/output switch useful for monitoring Equalizer Amp.
(For BD3816K1, available as an input function of the seventh line.)
11) Output mute controlled by either serial data or an external control terminal.
12) 2-wire serial control (For both 3.3V and 5V)
●Applications
AV receivers, home theater systems, and mini-audio systems.
●Line up matrix

Even in the specified range of Power Supply Voltage, applying voltage only to the VCC side may cause
an excessive current to give a permanent damage to the IC.
When starting up power supplies, VEE and VCC should be powered on simultaneously or VEE first; then followed by VCC.
Reduced by 12 mW/℃ over 25℃ (BD3816K1), when installed on the standard board (size: 70x70x1.6mm).

●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. VEE potential
Make the VEE pin voltage such that it is the lowest voltage even when operating below it. Actually confirm that the
voltage of each pin does not become a lower voltage than the VEE pin, including transient phenomena.
5. Thermal design
Perform thermal design, in which there are adequate margins, by taking into account the power 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. Operating Voltage Range and Operating Temperature Range
The circuit functional operations are guaranteed within the Operating Voltage Range and Operating Temperature Range.
The standard values of electrical characteristics, however, are guaranteed under the specific conditions. Accordingly,
careful consideration of the IC characteristic variations is required to design a set of circuit.
9. Power ON/OFF
(a) At power ON/OFF, a shock sound will be generated. Therefore, use MUTE on the set.
(b) When turning on power supplies, VEE and VCC should be powered on simultaneously, or VEE first followed by
VCC. If the VCC side is started up first, an excessive current may flow from VCC to VEE.
10. Serial control
For the CL and DA terminals, the patterned and other wirings should be routed as not to cause interference with
the analog-signal-related lines.
11. Function switching
For the all functions other than Master Volume, Treble, and Bass Gain Settings, use MUTE on the set.
