Product details

What this mono Class AB amp delivers

The Texas Instruments LM4906MM/NOPB is a Boomer® series Class AB audio amplifier in an 8-VSSOP package, delivering 1 W into an 8 Ω load from a single supply rail between 2.6 V and 5.5 V. Output is single-channel mono, which keeps the BOM lean for voice prompts, beepers, or single-speaker monitor circuits. The depop feature suppresses the turn-on thump that otherwise needs an external mute relay or soft-start capacitor — one less component to qualify.

Temperature range and environment

Rated for -40°C to 85°C ambient, this part handles outdoor telecom pedestals, factory-floor annunciators, and automotive cabin audio. The 8-VSSOP footprint (3.00 mm body width) fits tight layouts.

Frequently asked questions

Can LM4906MM/NOPB drive a 4 ohm load?

The datasheet specifies maximum output power as 1 W x 1 channel into 8 Ω. Driving a 4 Ω load is not covered by the listed rating; the part may deliver more current but thermal and distortion limits should be verified against the full datasheet.

What is the pinout of LM4906MM/NOPB?

The pinout is standard for a mono Class AB amplifier in an 8-VSSOP package: typically includes shutdown, bypass, input, output, and supply pins. The exact pin mapping is in the manufacturer's datasheet.

Where can I buy LM4906MM/NOPB and how do I get a price?

This part is sourced to order through independent distribution. Submit an RFQ for current pricing and availability — no stock count or price is listed here, but a quote request returns real-time market data.

What is the closest pin-compatible alternative to LM4906MM/NOPB in this component family?

The Boomer® family includes several mono Class AB amplifiers in the same 8-VSSOP footprint, such as the LM4861 and LM4863 series. Pin compatibility varies by shutdown and bypass pin assignments; verify the specific pinout against your layout before substituting.
