Product details

What this part is and where it fits

The LM49101TMX/NOPB is a Boomer® series Class AB audio subsystem. It integrates a mono speaker amplifier rated for 1.3W into 8Ω and a stereo headphone amplifier delivering 45mW per channel into 32Ω.

Output power split — what it means for the BOM

The 1.3W mono channel into 8Ω covers a small speaker driver for voice prompts or alert tones, while the 45mW stereo headphone output into 32Ω handles line-level or headphone listening. That split means a single IC replaces two separate amplifier stages, saving board area and reducing the passive count around the audio path. The I²C bus lets a host MCU adjust volume independently for speaker and headphones, which simplifies the control interface compared to analog-potentiometer designs.

Lifecycle and sourcing

The LM49101TMX/NOPB is listed as Active in production status. For current pricing and availability, this part is sourced and quoted to order through independent distribution — submit an RFQ and we confirm the lead time and price at quote.

Frequently asked questions

Can LM49101TMX/NOPB drive both an 8-ohm speaker and 32-ohm headphones?

Yes, the part has a dedicated 1.3W mono output for an 8Ω speaker and a separate stereo headphone output rated at 45mW per channel into 32Ω, both on the same IC.

What is the pinout of LM49101TMX/NOPB?

The pinout is defined in the TI datasheet for the 25-BGA (2.01x2.01) package. The ball map includes I²C lines, audio inputs, speaker and headphone outputs, supply and ground balls. Refer to the official datasheet for the exact ball assignment.

Is LM49101TMX/NOPB compatible with 3.3V logic?

The I²C interface operates within the 2.7V to 5.5V supply range, so 3.3V logic levels are compatible without level shifting.

Does LM49101TMX/NOPB require external components for operation?

The device integrates depop, thermal protection, and I²C volume control, but external input coupling capacitors and output filter components are typically needed per the application circuit in the datasheet.
