Sound processor for DVD player BD3824FS Description Dimension (Unit : mm) BD3824FS is a single chip IC for DVD recorder application. Each function of 5-channel input selector, input gain, tuner gain, ALC, line amplifier and power save ON/OFF can be controlled by I2C BUS. 1 16 Applications DVD recorder Absolute Maximum Ratings (Ta=25°C) Symbol Limits Maximum applied voltage Vcc 10.0 V Power dissipation Pd mW Topr 950 * D40 to +85 Tstg D55 Parameter Operating temperature range Storage temperature range Unit to +125 °C °C *Derating : 9.5mW/°C for operation above Ta=25°C *PCB (70mmX70mm,t=1.6mm) glass epoxy mounting. Operating Conditions (Ta=25°C) Parameter Supply voltage Symbol Min. Typ. VCC 7.0 9.0 Max. 9.5 Unit V 0.11 1) Low distortion rate and low noise 0.8 2) Built-in ALC circuit can be used as RF output 3) Perfect for low current consumption and energy saving design due to BiCMOS process 4) SSOP-A32 package. Layout terminals for audio input and audio output are located together to arrange the flow of signal in the same direction enabling an easy pattern layout and saving space on the board. 5) Same PCB board as BD3822FS is available. I2C BUS software of BD3822FS can be used without any modification. 6) Original system is applied, which its input (tuner, FRONT, EXT) waveform is not distorted at I2C BUS standby mode. 0.36±0.1 0.15±0.1 Features 1.8±0.1 17 5.4±0.2 7.8±0.3 13.6±0.2 32 0.3Min. 0.15 SSOP-A32 Electrical characteristics(Unless otherwise noted;Ta=25°C, Vcc=9V, f=1kHz, VIN=1Vrms, Rg=600W, RL1=4.7kW(LINEOUT1,2), RL2=10kW(OUT1, OUT2, RF OUT, Tuner1_0, 2_0), input terminal=Front1,Output terminal=OUT1, Gain amp=0dB, Tuner gain=0dB) Parameter Circuit current at no signal mode Symbol IQ Min. - Typ.
