Frequently Asked Questions
What type of speaker is the LM48823TL/NOPB designed to drive?
The LM48823TL/NOPB is specifically designed to drive ceramic and piezoelectric speakers using a bridge-tied load (BTL) configuration. The BTL output doubles the effective voltage across the speaker element compared to a single-ended driver, which is important for maximizing the acoustic output of high-impedance ceramic speakers that do not benefit from traditional dynamic speaker amplifier topologies.
How is the volume controlled on the LM48823TL/NOPB?
Volume is controlled digitally via the I2C interface, allowing a host microcontroller or application processor to adjust the output level in software without any analog potentiometers or external components. An integrated hardware reset pin also allows the audio output to be muted or the IC to be initialized at power-up.
What package does the LM48823TL/NOPB use and how small is it?
The LM48823TL/NOPB is housed in a 16-ball plastic BGA (Ball Grid Array) package measuring 4x4mm with a 20-mil (0.5mm) ball pitch. This square BGA package is one of the smallest available for audio ICs, enabling integration into the tightest smartphone and wearable PCB layouts.
Is the LM48823TL/NOPB RoHS compliant and lead-free?
Yes, the LM48823TL/NOPB carries a Pb-free code of Yes and a JESD-609 code of e1, confirming it is manufactured in a lead-free process fully compliant with RoHS and other environmental hazardous substance directives applicable to consumer electronics in the EU and globally.
