BD3823FV

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.
