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
