TECHNICAL NOTE Video / Audio Interfaces for TV and DVD Recorders NTSC-PAL Audio I/O Interface for Recording BD3823FV ƔDescription BD3823FV is a low-noise (3.2ҏμVrms), low distortion (0.0015%), 5ch selector, incorporating a resistor-ladder type volume. Because of a wide power supply voltage range (7V to 14.5V), BD3823FV can meet a wide input voltage (to 4.5 Vms), and high S/N can be achieved. In addition, the built-in volume does not add any distortion ratio characteristics, even when the attenution is varied, and is applicable for high-quality audio systems. ƔFeatures 1) A resistor-ladder type volume circuit is with a low distortion ratio (0.0015% with volume set to –6dB) and low noise (3.2 ȝVrms with volume set to -6dB). 2) By grouping sound input terminals with output terminals, the PCB layout is reduced. 3) Small package SSOP - B20 achieves good crosstalk characteristicss (-110 dB). 4) The use of Bi-CMOS process enables low current consumption and energy saving design. Because of low current consumption, BD3823FV has the advantage in quality over the scaling down of the internal regulators and heat controls.

Input terminal Fig.15 Sigal input section 2) SHORT mode of input SHORT mode is a command to reduce resistance by setting impedance RIN to switch SSH͛ON. When SHORT command is not chosen, switch SSH is turned OFF. By using this command, it is possible to stop charging externally mounted coupling capacitor C. Use SHORT mode when there is no signal since the SHORT mode turns ON the SSH switch in order to achieve low impedance. Ɣ Operation Notes 1. 2. 3. 4. 5. 6. 7. Numbers and data in entries are representative design values and are not guaranteed values of the items. 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. 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. 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. Thermal design Perform thermal design, in which there are adequate margins, by taking into account the permissible dissipation (Pd) in actual states of use. 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. Operation in strong electromagnetic field Using the ICs in a strong electromagnetic field can cause operation malfunction. ! 7/8 ƔSelection of order type B D 3 8 2 3 F V E 2 Tape and Reel information Part No. BD3823FV SSOP-B20 <Dimension> <Tape and Reel information> 20 11 0.3Min. 1 10 0.15 ± 0.1 2500pcs Direction of feed (Correct direction: 1pin of product should be at the upper left when you hold reel on the left hand, and you pull out the tape on the right hand) E2 0.1 1234 1234 1234 1pin 1234 1234 Reel 㧔Unit:mm) 1234 1234 0.65 0.22 ± 0.1 Embossed carrier tape 1234 6.4 ± 0.3 1.15 ± 0.1 4.4 ± 0.2 0.1 6.5 ± 0.2 Tape Quantity Direction of feed ̪Orders are available in complete units only.

Products listed in this document are no antiradiation design. The products listed in this document are designed to be used with ordinary electronic equipment or devices (such as audio visual equipment, office-automation equipment, communications devices, electrical appliances and electronic toys). Should you intend to use these products with equipment or devices which require an extremely high level of reliability and the malfunction of which would directly endanger human life (such as medical instruments, transportation equipment, aerospace machinery, nuclear-reactor controllers, fuel controllers and other safety devices), please be sure to consult with our sales representative in advance. It is our top priority to supply products with the utmost quality and reliability. However, there is always a chance of failure due to unexpected factors. Therefore, please take into account the derating characteristics and allow for sufficient safety features, such as extra margin, anti-flammability, and fail-safe measures when designing in order to prevent possible accidents that may result in bodily harm or fire caused by component failure. ROHM cannot be held responsible for any damages arising from the use of the products under conditions out of the range of the specifications or due to non-compliance with the NOTES specified in this catalog.
