The TAS6424M-Q1 device is
a four-channel digital-input Class-D audio amplifier that implements a 2.1 MHz
PWM switching frequency enabling a cost-optimized solution in a very small PCB size, full operation
down to 4.5 V for start/stop events, and exceptional sound quality with up to 40 kHz audio
The output switching frequency can be set either above the AM band, which eliminates
AM-band interferences and reduces output filtering and cost, or below the AM band to optimize
The device has a built-in load diagnostic function for detecting and diagnosing
misconnected outputs as well as detection of AC-coupled tweeters to help to reduce test time during
the manufacturing process.
The TAS6424M-Q1 Class-D audio amplifier is designed for use in
automotive head units and external amplifier modules. The device provides
channels at 27 W into 4 Ω at 10% THD+N and 45
W into 2 Ω at 10% THD+N from a 14.4 V supply.
For pin compatible one, two and four-channel
devices see the TAS6421-Q1, TAS6422-Q1, TAS6424L-Q1 and TAS6424-Q1.
