DIGITAL INPUT STEREO 20W DIGITAL AUDIO POWER AMPLIFIER
■Overview
YDA163C(D-515D) is a high-performance digital audio amplifier IC that delivers up to 20W×2ch, which
*1)
has a digital audio interface, and is capable of operating at a supply voltage ranging from 5V
YDA163C, having Yamaha original “Pure Pulse Direct Speaker Drive Circuit,” allows a speaker to be
directly connected to the output. In addition, this amplifier is insusceptible to supply voltage fluctuation
because of a feedback-type digital amplifier, and have the feature with high power supply noise tolerance.
As a result, power supply can be simplified and allowing a simple amplifier system with less external
components to be configured. YDA163C has the following functions: power limit function, pop noise
reduction function, overcurrent protection function for speaker output pins, internal overtemperature
protection function, under voltage lockout, and DC detection function. And, YDA163C supports power

PRECAUTIONS AND INSTRUCTIONS FOR SAFETY
WARNI NG
Do not use the device under stresses beyond those listed in Absolute Maximum Ratings.
Such stresses may become causes of breakdown, damages, or deterioration, causing explosion

or ignition, and this may lead to fire or personal injury.
Do not mount the device reversely or improperly and also do not connect a supply voltage in
wrong polarity. Otherwise, this may cause current and/or power-consumption to exceed the
absolute maximum ratings, causing personal injury due to explosion or ignition as well as causing
breakdown, damages, or deterioration.
And, do not use the device again that has been improperly mounted and powered once.
Do not short between pins.
In particular, when different power supply pins, such as between high-voltage and low-voltage
pins, are shorted, smoke, fire, or explosion may take place.
As to devices capable of generating sound from its speaker outputs, please design with safety of
your products and system in mind, such as the consequences of unusual speaker output due to a
malfunction or failure. A speaker dissipates heat in a voice-coil by air flow accompanying vibration
of a diaphragm. When a DC signal (several Hz or less) is input due to device failure, heat
dissipation characteristics degrade rapidly, thereby leading to voice-coil burnout, smoking or
ignition of the speaker even if it is used within the rated input value.

CAUTION
Do not use Yamaha products in close proximity to burning materials, combustible substances, or
inflammable materials, in order to prevent the spread of the fire caused by Yamaha products, and
to prevent the smoke or fire of Yamaha products due to peripheral components.
Generally, semiconductor products may malfunction and break down due to aging, degradation,
etc. It is the responsibility of the designer to take actions such as safety design of products and
the entire system and also fail-safe design according to applications, so as not to cause property
damage and/or bodily injury due to malfunction and/or failure of semiconductor products.
The built-in DSP may output the maximum amplitude waveform suddenly due to malfunction from
disturbances etc. and this may cause damage to headphones, external amplifiers, and human
body (the ear). Please pay attention to safety measures for device malfunction and failure both in
product and system design.
As semiconductor devices are not nonflammable, overcurrent or failure may cause smoke or fire.
Therefore, products should be designed with safety in mind such as using overcurrent protection
circuits to control the amount of current during operation and to shut off on failure.
Products should be designed with fail safe in mind in case of malfunction of the built-in protection
circuits. Note that the built-in protection circuits such as overcurrent protection circuit and
high-temperature protection circuit do not always protect the internal circuits. In some cases,
depending on usage or situations, such protection circuit may not work properly or the device
itself may break down before the protection circuit kicks in.
Use a robust power supply.
The use of an unrobust power supply may lead to malfunctions of the protection circuit, causing
device breakdown, personal injury due to explosion, or smoke or fire.
Product's housing should be designed with the considerations of short-circuiting between pins of
the mounted device due to foreign conductive substances (such as metal pins etc.). Moreover,
the housing should be designed with spatter prevention etc. due to explosion or burning.
Otherwise, the spattered substance may cause bodily injury.
The device may be heated to a high temperature due to internal heat generation during
operation. Therefore, please take care not to touch an operating device directly.
