Datasheet Sound Processor for Car Audio with Built-in High-Voltage Amplifier and nd 2 Order Post Filter BD37069FV-M (Note2) General Description Key Specifications BD37069FV-M is a sound processor developed for car Total Harmonic Distortion: 0.003%(Typ) audio with built-in selector of six stereo inputs and output Maximum Input Voltage: 2.1V (Typ) RMS interfaced to ADC after adjusting signal level. Common Mode Rejection Ratio : 55dB(Min) BD37069FV-M has a 6-channel volume circuit and Maximum Output Voltage: 5.2V (Typ) RMS nd built-in 2 order post filter which reduces the out-of Output Noise Voltage: 23V (Typ) RMS -band noise. The High-Voltage function is capable to Residual Output Noise Voltage: 10.5V (Typ) RMS reach up to 5.2V maximum output. Furthermore, the Ripple Rejection Ratio: -70dB (Typ) RMS IC is simple to design due to the built-in TDMA noise Operating Temperature Range: -40C to +85C (Note2)These specifications are High-Voltage mode2. reduction systems. Features (Note1) Package AEC-Q100 Qualified W(Typ) x D(Typ) x H(Max) Built-in differential input selector that can select SSOP-B40 13.60mm x 7.80mm x 2.00mm single-ended / differential input Reduce switching pop noise of input gain control due to the built-in advanced switch circuit nd Less out-of-band noise of DAC by built-in 2 order post filter Built-in buffered ground isolation amplifier to achieve high CMRR characteristics Built-in TDMA noise reduction circuit reduces the additional components for external filter Available to output 5.2V by High-Voltage function RMS (This device is possible to 3.2V output by using RMS another High-Voltage mode, VCCH=11.5V) 2 Available to control by 3.3V / 5V for I C-bus controller Applications The input and output terminals are located together to Car Audio and Other Audio Equipment arrange the flow of signal in a same direction making the PCB layout easier and PCB area smaller (Note 1) Grade 3 Typical Application Circuit DSP ADC DAC IG1 IG2 INF2 INF1 INR2 INR1 INS INC A1 BD37069FV-M CD Main Gain adjust Sub Gain adjust A2 B1 Fader 2nd order Fader Level USB boost LPF OUTC B2 ATT Shift CP1 Fader 2nd order Fader Sub SEL LPF boost ATT CN Level OUTS TUN Shift CP2 DP1 Fader Level OUTR1 Fader 2nd order DN Shift AUX LPF ATT boost DP2 Rear SEL 2nd order Fader Fader Level OUTR2 EP1 LPF Shift boost ATT EN AUX EP2 Fader 2nd order Fader Level OUTF1 boost LPF Shift ATT FP1 Front SEL FN1 2nd order Fader Fader Level OUTF2 BT FN2 boost LPF Shift ATT FP2 Advanced Switch MIN NAVI Figure 1.
