The Texas Instruments TAS5342LDDVR is a 100-W stereo digital amplifier power stage designed for audio applications. It operates with a PWM input and supports up to 4 speaker channels. The device features a Class-D architecture, providing high efficiency exceeding 90% with low 110mΩ output MOSFETs.
Key electrical specifications include a power stage supply voltage range of 0 to 34 V and an analog supply voltage range of 10.8 to 13.2 V. It offers a minimum load impedance of 2 Ω and a typical RDS(on) of 0.11 Ω. The amplifier delivers significant power output, with 2 x 100 W into 4 Ω in bridge-tied load configuration, 4 x 40 W into 3 Ω in single-ended mode, and 1 x 200 W into 2 Ω in parallel mode, all at 10% THD+N.
Further performance highlights include a signal-to-noise ratio (SNR) greater than 110 dB (A-weighted) and total harmonic distortion plus noise (THD+N) of less than 0.1% at 1 W and 1 kHz. The device supports PWM frame rates from 192 kHz to 432 kHz. It is housed in a 44-pin HTSSOP (DDV) package, measuring 14 mm x 8.1 mm, with a package area of 113.4 mm².
Integrated self-protection circuitry includes under-voltage protection, overtemperature warning and error, overload protection, short-circuit protection, and a PWM activity detector. It also features power-on reset to eliminate system power-supply sequencing issues. The operating temperature range is from 0°C to 70°C. This part is supplied in tape and reel packaging with a standard quantity of 2000 units.
