LV4904V
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 = 8), 15W × 2 channels (PVD = 18V, RL = 8)
Efficiency
: 85% (PVD = 15V, RL = 8, fin = 1 kHz, Po = 10W)
THD + N
: 0.1% or less (PVD = 15V, RL = 8, fin = 1 kHz, Po = 1W, filter: AES17)
Power supply voltages
: PVD = 8 to 20V, VDD = 3.3V
Ordering number: ENA1963
