Product Overview
The TAS5805 is a Texas Instruments stereo Class-D audio amplifier in the Signal_Chain category. It operates from a recommended PVDD range of 4.5 V to 26.4 V and supports DVDD and I/O configurations at 1.8 V or 3.3 V, with a DVDD recommended operating range of 1.62 V to 3.63 V.
For output capability, the device is specified for 2 x 23 W in 2.0 mode with an 8-ohm load at PVDD=21 V and THD+N=1%, or 45 W in mono mode with a 4-ohm load under the same PVDD and distortion condition. At 1 W, 1 kHz, and PVDD=12 V, THD+N is specified at <=0.03%, with A-weighted SNR >=107 dB and noise level <40 uVrms.
The digital audio interface supports I2S, LJ, RJ, TDM, and 3-wire formats without requiring MCLK. Supported input sample rates are 32, 44.1, 48, 88.2, and 96 kHz, while the integrated audio processor uses a 96 kHz architecture. The package is a 28-pin TSSOP PWP with a 9.7 mm x 4.4 mm nominal body.
