• Total Power Output (Bridge Tied Load)
– 2 × 100 W at 10% THD+N Into 4 Ω
The TAS5342 is a high-performance, integrated
stereo digital amplifier power stage designed to drive
– 2 × 80 W at 10% THD+N Into 6 Ω
a 4- Ω bridge-tied load (BTL) at up to 100 W per
– 2 × 65 W at 10% THD+N Into 8 Ω
channel with low harmonic distortion, low integrated
• Total Power Output (Single Ended)
noise, and low idle current.
– 4 × 40 W at 10% THD+N Into 3 Ω
The TAS5342 has a complete protection system
– 4 × 30 W at 10% THD+N Into 4 Ω
integrated on-chip, safeguarding the device against a
wide range of fault conditions that could damage the
• Total Power Output (Parallel Mode)
system. These protection features are short-circuit
– 1 × 200 W at 10% THD+N Into 2 Ω
protection, over-current protection, under voltage
– 1 × 160 W at 10% THD+N Into 3 Ω
protection, over temperature protection, and a loss of
PWM signal (PWM activity detector).
• >110 dB SNR (A-Weighted With TAS5518
Modulator)
A power-on-reset (POR) circuit is used to eliminate
power-supply sequencing that is required for most
• <0.1% THD+N (1 W, 1 kHz)
power-stage designs.
• Supports PWM Frame Rates of 192 kHz to

• Resistor-Programmable Current Limit
SUPPLY VOLTAGE
• Integrated Self-Protection Circuitry, Including:
– Under Voltage Protection
– Overtemperature Warning and Error
– Overload Protection
– Short-Circuit Protection
– PWM Activity Detector
• Standalone Protection Recovery
• Power-On Reset (POR) to Eliminate System
Power-Supply Sequencing
• High-Efficiency Power Stage (>90%) With
80-m Ω Output MOSFETs
• Thermally Enhanced Package 44-Pin HTSSOP
(DDV)
• Error Reporting, 3.3-V and 5.0-V Compliant
• EMI Compliant When Used With
Recommended System Design
