Overview
The LV4904V is a 2-channel 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 I²C bus interface, but it is also possible to establish these settings simply
by pin settings without using the I²C bus. The LV4904V is ideally suited as the power amplifiers in mini components,
flat-panel TVs, game machines, electronic musical instruments and other such products.
Features
• I²S input, 2-channel class-D power amplifier
• On-chip variable over-sampler
• Gain controller (+12dB to -81dB, in 1.5 dB increments)
• Soft mute function
• Controllable via I²C bus or pin settings
• Under voltage protection circuit, overcurrent protection circuit, thermal protection circuit integrated
Functions
• Input PCM (Fs): 32 kHz/44.1 kHz/48 kHz/88.1 kHz/96 kHz/176.2 kHz/192 kHz
• Master clock input: 256 fs/384 fs/512 fs/768 fs (when Fs=32/44.1/48 kHz)
• Input format: I²S/24 bits left justified MSB-first / 24 bits right justified LSB-first / 16/18/20/24 bits right justified
MSB-first
• Output (THD + N=10%) : 10W × 2 channels (PVD = 15V, RL = 8Ω), 15W × 2 channels (PVD = 18V, RL = 8Ω)
• Efficiency
: 85% (PVD = 15V, RL = 8Ω, fin = 1 kHz, Po = 10W)
• THD + N
: 0.1% or less (PVD = 15V, RL = 8Ω, fin = 1 kHz, Po = 1W, filter: AES17)
• Power supply voltages : PVD = 8 to 20V, VDD = 3.3V
