Amplifier IC 2-Channel (Stereo) Class D 44-HTSSOP

TPA3255DDVR General Description

In addition to its impressive audio performance, the TPA3255DDVR also boasts high power efficiency and low power stage idle losses. By using 85 mΩ MOSFETs and an optimized gate driver scheme, this amplifier is able to achieve idle losses below 2.5W, significantly lower than other similar products on the market. This not only results in energy savings but also ensures that the amplifier operates at peak performance levels
