Product Overview
TAS5825M is a Texas Instruments digital input Class-D audio amplifier for Signal_Chain designs using digital audio interfaces. The device supports I2S, left-justified, right-justified, and TDM input formats, with sample rates of 32, 44.1, 48, 88.2, 96, and 192 kHz. A 3-wire digital audio interface is supported without MCLK, and device configuration is handled through I2C software control.
The amplifier operates from a 4.5 V to 26.4 V PVDD recommended range and supports 1.8 V or 3.3 V digital supply operation, with a DVDD recommended range of 1.62 V to 3.63 V. Output specifications include 1 x 53 W at 1% THD+N and 1 x 65 W at 10% THD+N in 1.0 mode with 4 ohm load, plus 2 x 30 W and 2 x 38 W in 2.0 mode with 8 ohm load.
The VQFN (32) RHB package measures 5.00 mm x 5.00 mm. Design limits include BTL speaker loads down to 3.2 ohm minimum and PBTL loads down to 1.6 ohm minimum, with a 1 uH minimum LC filter inductor under short-circuit conditions.
