Datasheet LC75410W, LC75410E Datasheet (SANYO)

Ordering number : ENN7027

O1901RM (OT) No. 7027-1/28

Overview

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.

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.

Features

• 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)

When –∞ data is sent to the main volume, S1 and S2
become open, and S3 and S4 simultaneously become ON.

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.

(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.

Volume block

D36 D37 D38 D39

0 0 1 0

(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

Normally, a value between 10 ms and 50 ms is set.

(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.

This catalog provides information as of October, 2001. Specifications and information herein are subject
to change without notice.

Specifications of any and all SANYO products described or contained herein stipulate the performance,
characteristics, and functions of the described products in the independent state, and are not guarantees
of the performance, characteristics, and functions of the described products as mounted in the customer’s
products or equipment. To verify symptoms and states that cannot be evaluated in an independent device,
the customer should always evaluate and test devices mounted in the customer’s products or equipment.

SANYO Electric Co., Ltd. strives to supply high-quality high-reliability products. However, any and all
semiconductor products fail with some probability. It is possible that these probabilistic failures could
give rise to accidents or events that could endanger human lives, that could give rise to smoke or fire,
or that could cause damage to other property. When designing equipment, adopt safety measures so
that these kinds of accidents or events cannot occur. Such measures include but are not limited to protective
circuits and error prevention circuits for safe design, redundant design, and structural design.

In the event that any or all SANYO products (including technical data, services) described or contained
herein are controlled under any of applicable local export control laws and regulations, such products must
not be exported without obtaining the export license from the authorities concerned in accordance with the
above law.

No part of this publication may be reproduced or transmitted in any form or by any means, electronic or
mechanical, including photocopying and recording, or any information storage or retrieval system,
or otherwise, without the prior written permission of SANYO Electric Co., Ltd.

Any and all information described or contained herein are subject to change without notice due to
product/technology improvement, etc. When designing equipment, refer to the “Delivery Specification”
for the SANYO product that you intend to use.

Information (including circuit diagrams and circuit parameters) herein is for example only; it is not
guaranteed for volume production. SANYO believes information herein is accurate and reliable, but
