MONAURAL 2.6W Non-Clip DIGITAL AUDIO POWER AMPLIFIER
YDA158 CATALOG
Outline
The YDA158 (D-4HP2) is a 2.6W (RL=4）×1ch Class-D amplifier with a capless stereo headphone
amplifier and receiver output. Its superior sound quality, the lowest level of distortion and noise are achieved
by “Pure Pulse Direct Speaker Drive Circuit” which does not need a number of components such as a LC
filter.
The YDA158 features "Non-Clip2" and “Power Limit” circuits which were developed by Yamaha. The
circuits automatically detect and prevent clipping noise by shortage of supply voltage. Moreover, it is
possible to set the THD level to control sound pressure.
The YDA158 has the I2C interface to control input volume, mixer, output level attenuator, power-down
mode, etc. In addition, the protect function (over current, high temperature, low supply voltage malfunction),
the pop noise reduction, the EMI noise reduction and the superior PSRR against TDMA (GSM) are
equipped.
