TPA3200D1 - 20-W MONO DIGITAL INPUT AUDIO AMPLIFIER

Description

The TPA3200D1 is a 20-W (per channel) efficient, digital audio power amplifier for driving a bridged-tied speaker.

The TPA3200D1 can drive a speaker with an impedance as low as 4 Ω.

The high efficiency of the TPA3200D1 (85%) eliminates the need for an external heat sink.
