Page 26 TENTATIVE 8. Explanation for the functions 1. Standby switch function (pin 4) Threshold voltage of the pin 4 is set by about 2VBE. The amplifier is turned on by the applied voltage of 2.5V or more. Also, the amplifier is turned off by the applied voltage of 0.5V or less.
Page 27 TENTATIVE 4. Self-diagnosis function (pin 25) By detecting the unusual state of the IC, the signal is output to the pin 25. Also, by controlling the standby switch after the signal of the pin 25 is detected by the microcomputer, the burnout of the speaker can be prevented.

Page 40 TDA7419 AutoZero The AutoZero allows a reduction of the number of pins as well as external components by canceling any offset generated by or before the In-Gain-stage (Please notice that externally generated offsets, e.g. gen- erated through the leakage current of the coupling capacitors, are not canceled). The auto-zeroing is started every time the input source is changed and needs max.

Page 42 TDA7419 5.3.4 Flat Mode In flat mode the loudness stage works as a 0dB to -15dB attenuator. SoftMute The digitally controlled SoftMute stage allows muting/demuting the signal with a I C-bus programmable slope. The mute process can either be activated by the SoftMute pin or by the I C-bus.

Inaddition the pro- grammed center frequency and quality factor is decreased by 25% which can be used to reach alternative cen- ter frequencies or quality factors.

Figure 14. Middle Control @ f = 1 kHz, Q = 1 5.7.2 Center Frequency Figure 14 shows the four possible center frequencies 500Hz, 1kHz, 1.5kHz and 2.5kHz.

Middle Quality factors @ Gain = 14dB, fc = 1kHz Treble There are two parameters programmable in the treble stage: 5.8.1 Attenuation Figure 16 shows the attenuation as a function of frequency at a center frequency of 17.5kHz.

Treble Center Frequencies @ Gain = 15dB 1 0 K 1 0 0 Subwoofer Filter The subwoofer lowpass filter has butterworth characteristics with programmable cut-off frequency (80/ 120/160Hz) Figure 19.
Page 48 TDA7419 5.10 Spectrum Analyzer A fully integrated seven-band spectrum analyzer with programmable quality factor is present. The spec- trum analyzer consists of seven band pass filters with rectifier and sample capacitor that stores the max- imum peak signal level since the last read cycle. This peak signal level can be read by a microprocessor at the SAout-pin.
Page 49 TDA7419 5.11 AC-Coupling In some applications additional signal manipulations are desired, such as additional band equalizations. For this purpose, an AC-Coupling can be placed before the loudness attenuator or speaker-attenuators, which can be activated or internally shorted by I C-Bus. In short condition, the input-signal of the speaker- attenuator is available at the AC-Outputs.
Page 50 TDA7419 5.13 Output Selector and Mixing The output-selector allows the front and rear speakers to connect to different sources. The setup of the output selector is shown in Figure 24. A Mixing-stage is placed after the front speaker-attenuator and can be set to mixing-mode.

Page 66 TDA7703/TDA7703R 5.0 FUNCTION DESCRIPTION 5.1 FM-Mixer The IMR mixer is optimized for optimum performance in case of a passive tuned prestage and for a passive fixed bandpass without tuning for low-cost application. The input frequency is downconverted to low IF with high image rejection. 5.2 FM - AGC The programmable RFAGC senses the mixer input, the IFAGC senses the IFADC input to avoid overload.
Page 67 TDA7703/TDA7703R 5.12 I C ADDRESS SELECTION / RDS INTERRUPT INTERFACE PIN As explained also in 5.13.1, there is one pin (RDSINT, pin 29) dedicated to selecting the I address of the device. In the TDA7703R only this pin serves the additional function of RDS interrupt output to communicate to the uP when a new RDS block is available.
Page 68 TDA7703/TDA7703R a chip address byte must be sent at the beginning of the transmission.
