Description for the LM48861

The LM48861 is a single supply, ground-referenced stereo headphone amplifier. Part of TI's PowerWise product family, the LM48861 consumes only 3mW of power, yet still provides great audio performance. The ground-referenced architecture eliminates the larger DC blocking capacitors required by traditional headphone amplifier's saving board space and reducing cost.

The LM48861 features common-mode sensing that corrects for any differences between the amplifier ground and the potential at the headphone return terminal, minimizing noise created by any ground mismatches.

The LM48861 delivers 22mW/channel into a 32Ω load with <1% THD+N with a 1.8V supply. Power supply requirements allow operation from 1.2V to 2.8V. High power supply rejection ratio (PSRR), 83dB at 217Hz, allows the device to operate in noisy environments without additional power supply conditioning. A low power shutdown mode reduces supply current consumption to 0.01µA.

Superior click and pop suppression eliminates audible transients on power-up/down and during shutdown. The LM48861 is available in an ultra-small 12-bump, 0.4mm pitch, DSBGA package (1.215mm x 1.615mm).

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships  tube or tray  devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
