Ordering number : ENN7027 CMOS IC LC75410E, 75410W Electronic Volume Controller for Car Audio Systems Overview Features The LC75410E and 75410W are electronic volume controllers that enable control of volume, balance, fader, bass/treble/mid, loudness, input switching, and input gain using only a small number of external components. • On-chip buffer amplifier cuts down number of external components • Low switching noise generated by on-chip switch through use of silicon gate CMOS process, for low switching noise when there is no signal • Low switching noise when there is a signal due to use of on-chip zero-cross switching circuit • On-chip 1/2 VDD reference voltage circuit • Controls performed with serial input (CCB) Functions • Volume: 0 dB to –79.5 dB in 0.5-dB steps, and –∞ (161 positions) Balance function with separate L/R control • Fader: rear output or front output can be attenuated across 16 positions (in 1-dB steps from 0 dB to –2 dB, 2-dB steps from –2 dB to –20 dB, 10-dB steps from –20 dB to –30 dB, and –45 dB, –60 dB, –∞) • Bass/treble/mid: Each band can be controlled in 1-dB steps from 0 dB to ±6 dB, and in 2-dB steps from ±8 dB to ±12 dB. • Input gain: 0 dB to +18.75 dB (1.25-dB steps) amplification is possible for the input signal. • Input switching: five input signals can be selected for Left and for Right (Four are singleended inputs and one is a differential input.) • Loudness: A tap is output from the –32 dB position of a 2 dB step volume control resistor ladder. A loudness function can be implemented by connecting an external RC circuit. • CCB is a trademark of SANYO ELECTRIC CO., LTD. • CCB is SANYO’s original bus format and all the bus addresses are controlled by SANYO.

No. 7027-21/28 LC75410E, 75410W Usage Cautions (1) Data transmission at power ON • The status of internal analog switches is unstable at power ON. Therefore, perform muting or some other countermeasure until the data has been set. • At power ON, initial setting data must be sent once in order to stabilize the bias of each block in a short time. (2) Description of zero-cross switching circuit operation The LC75410E and 75410W have a function to switch zero-cross comparator signal detection locations, enabling the selection of the optimum detection location for blocks whose data is to be updated. Basically, the switching noise can be minimized by inputting the signal immediately following the block whose data is to be updated to the zero-cross comparator, so it is necessary to switch the detection location every time. Volume Selector Tone Fader Switch Zero-cross comparator LC75410E, 75410W Zero-Cross Detection Circuit (3) Zero-cross switching control method The zero-cross switching control method consists of setting the zero-cross control bits to the zero-cross detection mode (D36, D37 = 0), and specifying the detection blocks (D38, D39) before transmitting the data. These control bits are latched immediately following data transfer, that is to say beforehand in sync with the falling edge of CE, so when updating data of volumes, etc., it is possible to perform mode setting and zero-cross switching with one data transfer. An example of control when updating the data of the volume block is shown below. D36 D37 D38 D39 0 0 1 0 Zero-cross detection mode setting Volume block setting (4) Zero-cross timer setting If the input signal becomes lower than the zero-cross comparator detection sensitivity, or if only low-frequency signals are input, zero-cross detection continues to be impossible, and data is not latched during this time. The zero-cross timer can set a time for forcible latch during such a status when zero-cross detection is not possible. For example, to set 25 ms, using T = 0.69CR and C = 0.033 µF, we obtain R= 25 × 10 –3 0.69 × 0.033 × 10 –6 1.1 MΩ Normally, a value between 10 ms and 50 ms is set. No. 7027-22/28 LC75410E, 75410W (5) Cautions related to serial data transfer 1. To ensure that the high-frequency digital signals transferred to the CL, DI, and CE pins do not spill over to the analog signal block, either guard these signal lines with a ground pattern, or perform transmission using shielded wires. 2. The data format of the LC75410E and 75410W uses 8-bit addresses and 44-bit data. When sending data using multiples of 8 (when sending 48 bits), use the method described in Figure 1.
