LM4875MX/NOPB Description

Short technical summary and product information.

The Texas Instruments LM4875MX/NOPB is a mono bridged audio power amplifier featuring analog input and Class-AB architecture. It is capable of delivering 750mW of continuous average power into an 8Ω load with less than 1% THD when powered by a 5V supply.

Key electrical specifications include a power stage supply range of 2.7V to 5.5V and an analog supply voltage range of 2.7V to 5.5V. The amplifier exhibits a typical THD+N of 0.6% at 1kHz and a minimum load impedance of 8Ω. It also features a micropower shutdown mode with a typical shutdown current of 0.7µA, activated when less than 300mV is applied to the DC Vol/SD pin.

This audio amplifier includes precision DC voltage volume control and a headphone amplifier mode. It also incorporates "click and pop" suppression and shutdown control when the Volume Control pin is low, along with thermal shutdown protection. The device supports switching between bridged speaker mode and headphone (single-ended) mode via a headphone sense pin.

Available in VSSOP (DGK) and SOIC (D) packages, the LM4875MX/NOPB is designed for applications requiring high power audio output with high fidelity, operating on low supply voltages and requiring few external components.
