LV4904V Datasheet | onsemi

Ordering number: ENA1963 Monolithic IC Digital Input Class-D Power Amplifier http://onsemi. 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 ponents, 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 ponents, 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 (+12d B to -81d B, in 1.5 d B 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 k Hz/44.1 k Hz/48 k Hz/88.1 k Hz/96 k Hz/176.2 k Hz/192 k Hz - Master clock input: 256 fs/384 fs/512 fs/768 fs (when Fs=32/44.1/48 k Hz) - 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 k Hz, Po = 10W) - THD + N : 0.1% or less (PVD = 15V, RL = 8Ω, fin = 1 k Hz, Po = 1W, filter: AES17) - Power supply voltages : PVD = 8 to 20V, VDD = 3.3V Semiconductor ponents Industries, LLC, 2013 May, 2013 92811 SY 20110606-S00002 No.A1963-1/30 Specifications...
