LA4814JA

Ordering number : ENA2040 LA4814JA Monolithic Linear IC 2-Channel Power Amplifier http://onsemi.com Overview The LA4814JA buili-in the power amplifier circuit capable of low-voltage (2.7V and up) operation and has additionally a standby function to reduce the current drain. It is a power amplifier IC optimal for speaker drive used in battery-driven portable equipment and other such products. Applications Mini radio cassette players/recorders, portable radios, transceivers and other portable audio devices Features On-chip 2-channel power amplifier Output power 1 = 350mW typ. (VCC = 5.0V, RL = 4Ω, THD = 10%) Output power 2 = 150mW typ. (VCC = 3.6V, RL = 4Ω, THD = 10%) Enables monaural BTL output system by changing externally connected components Output power 3 = 700mW typ. (VCC = 5.0V, RL = 8Ω, THD = 10%) Output power 4 = 320mW typ. (VCC = 3.6V, RL = 8Ω, THD = 10%) Low-voltage operation possible VCC =2.7V and up Standby function Current drain at standby = 0.1μA typ. (VCC = 5V) Voltage gain setting possible Voltage gain = 3 to 20dB Second amplifier stop control function Reducing the pop noise at startup (in BTL mode) Semiconductor Components Industries, LLC, 2013 May, 2013 32812 SY 20111215-S00001 No.A2040-1/16 LA4814JA Specifications Maximum Ratings at Ta = 25°C Parameter Symbol Conditions Maximum supply voltage Allowable power dissipation VCC max Pd max * Maximum junction temperature Tj max Operating temperature Topr Storage temperature Tstg * Mo...
