Product Overview LA4814JA: Audio Power Amplifier, Class AB, 2-Channel, 0.35 W For complete documentation, see the data sheet Product Description 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. 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) Applications • Mini radio cassette players/recorders, portable radios, transceivers and other portable audio devices Part Electrical Specifications Product Compliance Status Class Output VCC Max Power Typ (V) (W) Output Type LA4814JA-AE Pb-free Active AB 0.35 7 LA4814JA-ZE Pb-free Active AB 0.35 7 ton Typ (ms) THD + N Typ (%) IQ Typ (mA) ISD Typ (nA) Package Type Dual 0.35 8.6 100 SSOP-20 Dual 0.35 8.6 100 SSOP-20 For more information please contact your local sales support at www.onsemi.com Created on: 6/30/2016
