Description
General part information
LM49153 Series
The LM49153 is a fully integrated audio subsystem designed for portable handheld applications such as cellular phones. Part of Texas Instruments' PowerWise family of products, the LM49153 combines an earpiece switch, a high efficiency 25mW class G headphone amplifier, and a high efficiency 1.35W class D loudspeaker into a single device.
The headphone amplifiers feature Texas Instruments' class G ground referenced architecture that creates a ground-referenced output with dynamic supply rails for optimum efficiency. The class D amplifier features an ALC (Automatic Level Control) with a noise gate that provides both no-clip and speaker protection.
Mode selection, shutdown control, and volume are controlled through an I2C compatible interface.
