LV49157V
LC01707PLF
Class-D Audio Power Amplifier
with built-in Headphone Amplifier
BTL 15W × 2ch
http://onsemi.com
Overview
The LV49157V is a 15W per channel stereo digital power amplifier that takes analog inputs. The LV49157V uses
unique Our developed feedback technology to achieve excellent audio quality despite being a class D amplifier and can
be used to implement high quality flat display panel (FDP) based systems.
Features
• BTL output, class D amplifier system
• Unique Our developed feedback technology achieves superb audio quality
• High-efficiency class D amplifier
• Soft muting function reduces impulse noise at power on/off
• Full complement of built-in protection circuits : over current protection, thermal protection, and low power supply
voltage protection circuits
• Built in Power limiter
• Built in Headphone Amplifier
Functions
• Power : 15W × 2ch output (VD = 15V, RL = 8Ω, fin = 1kHz, AES17, THD + N = 10%)
• Efficiency : 93% (VD = 15V, RL = 8Ω, fin = 1kHz, PO = 15W)
• THD + N : 0.08% (VD = 15V, RL = 8Ω, fin = 1kHz, PO = 1W, Filter : AES17)
• Noise : 90μVrms (Filter : A-weight)
• 60mW Stereo headphone Amplifier (VD = 15V, RL = 16Ω, THD + N = 10%)
• Package SSOP44J (275mil)

Operation Mode Summary
LV49157V
STBY mode (STBY = L, MUTE = L and HP_STBY = L)
Each bias becomes off state when the regulator in IC has been turned off.
The most of circuits becomes off state.
The supply current : 1μA (typical).
MUTE mode (STBY = H and MUTE = L)
Each bias becomes on state when the regulator in IC has been turned on.
When more than half of the circuits are active, the amplifier in the output stages become off.
The supply current : 20mA (typical).
Operation mode (STBY = H, MUTE = H and HP_STBY = H)
The LV49157V operates as D-class amplifier and Headphone amplifier.
The output signal is synchronized with the input signal.
The current of the main amplifier is 45mA (typical) in our recommendation condition, and the current of the headphone
amplifier is 8mA (typical) at RG=0.
