If you should intend to use our products for new introduction or other application different from current conditions on the usage of automotive device, communication device, office equipment, industrial equipment etc. , please consult with us about usage condition (temperature, operation time etc.) prior to the intended use. If there is no consultation or inquiry before the intended use, our customer shall be solely responsible for the use. 32812 SY 20111215-S00001 No.A2040-1/16 LA4814JA 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 = 0.1 μA 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) Monolithic Linear IC 2-Channel Power Amplifier Ordering number : ENA2040 |
