Frequently Asked Questions
How is the gain selected on LM4876?
LM4876 offers two fixed gain settings via the GAIN pin: connect to GND for 6dB (2V/V) or to VDD for 12dB (4V/V). No external gain-setting resistors are needed, simplifying design and reducing BOM cost compared to variable-gain amplifiers.
What speaker impedance is recommended for LM4876?
LM4876 is optimized for 4Ω and 8Ω speakers. Maximum power is 2.4W into 4Ω at 5V supply. With 8Ω speakers, output power is approximately 1.25W. Minimum load impedance is 3.2Ω to stay within thermal limits.
How does LM4876 differ from LM4871?
LM4876 offers selectable fixed gain (6/12dB via pin) while LM4871 requires external resistors for gain setting. LM4871 provides slightly higher power (3W vs 2.4W at 4Ω). Choose LM4876 for simpler design, LM4871 for more output power.
What is the power supply requirement for LM4876?
LM4876 operates from 2.4V to 5.5V single supply. Typical applications use 3.3V or 5V. Bypass VDD with a 1µF capacitor and connect a 1µF capacitor on the BYPASS pin for the internal mid-supply reference. Total quiescent current is 5mA.
