Figure 4-12. Microphone Input
The SAM3S-EK evaluation kit supports mono/stereo audio playback driven by a TPA0223 audio ampli-
fier connected to two DAC channels of the microcontroller.
The TPA0223 is a 2W mono Bridge-Tied-Load (BTL) amplifier designed to drive speakers with as low as
4 Ohm impedance. The amplifier can be reconfigured on the fly to drive two stereo Single-Ended (SE)
signals into head phones.
