DESCRIPTION

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

鈩?

The TAS5182 device,

incorporating Texas Instrument鈥檚 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.
