The TAS5182 device is a high-performance, stereo digital
amplifier power stage controller. It is designed to drive two
discrete bridge-tied-load (BTL) MOSFET output stages at
up to 100 W per channel at 6 Ω. The TAS5182 device,
incorporating Texas Instrument’s PurePatht technology,
is used in conjunction with a digital audio PWM processor
(TAS50XX) and two discrete MOSFET H-bridges
(4 MOSFETs per H-Bridge) to deliver high-power, true
digital audio amplification. The efficiency of this digital
amplifier can be greater than 95%, reducing the size of
both the power supplies and heat sinks needed. The
TAS5182 device accepts a stereo PWM 3.3-V input, and
it controls the switching of the discrete H-bridges.
Overcurrent, overtemperature, and undervoltage
protections are built into the TAS5182 device,
safeguarding the H-bridge and speakers against output
short-circuit conditions, overtemperature conditions, and
other fault conditions that could damage the system.

These devices have limited built-in ESD protection. The
leads should be shorted together or the device placed in
conductive foam during storage or handling to prevent
electrostatic damage to the MOS gates.
