LA4814V
Overview
The LA4814V 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 : ENA0972
