Product Overview
TS5USBA224 is a Texas Instruments USB audio analog switch for Signal_Chain designs. Its core function is a double-pole double-throw multiplexer that combines a USB 2.0 high-speed switch with an audio switch, allowing USB D+/D- and audio L/R paths to be controlled through ASEL and VBUS logic inputs.
For USB operation, the device supports 480 Mbps data rate, 650 MHz typical -3 dB bandwidth, 12.5 pF typical on capacitance, 2.8 pF typical off capacitance, and 35 ps typical channel-to-channel skew at 240 MHz. USB switch on resistance is 4 Ohm typical and 7 Ohm maximum under the stated 3 V VAUDIO and 5 V VBUS condition.
For audio switching, TS5USBA224 provides 3 Ohm typical and 5 Ohm maximum on resistance, 15 pF typical on capacitance, 4.5 pF typical off capacitance, -83 dB typical crosstalk, and 0.05% typical THD across 20 Hz to 20 kHz. The device operates from a 2.7 V to 5.5 V VAUDIO supply and is offered in a 10-pin RSW QFN package for compact assembly.
