LV4904VGEVB

LV4904VGEVB is a evaluation board for LV4904V class-D amplifier IC that supports digital input. With this single chip and with a minimal number of external components, it is possible to effectively implement class-D amplifiers. The LV4904V incorporates a soft mute function and a gain controller without pop noise, and can be used as a master volume control of the set. Its function settings can be established through an IIC bus interface, but it is also possible to establish these settings simply by pin settings without using the IIC bus.

• IIS input, 2 channel class-D power amplifier
• On chip variable over sampler
• Gain controller (+12dB to -81dB, in 1.5dB increments)
• Soft mute function
• Controllable via IIC bus or pin settings
• Under voltage, overcurrent, thermal protection circuit integrated
