4.3.14  Audio Interface 

The Atmel SAM4E-EK evaluation kit supports mono/stereo audio driven by a TPA0223 audio amplifier 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

Ω

 

impedance. The amplifier can be reconfigured on the fly to drive two stereo Single-Ended (SE) signals into head 
phones.

Using a readily available 1/8-in. (3.5mm) stereo headphone jack, the control switch (pin4 and pin5 in J10) is closed 
when no plug is inserted. When closed, a 100k

Ω

/1k

Ω

 divider pulls the ST/MN input low. When a jack plug is inserted, 

the 1k

Ω

 resistor is disconnected and the ST/MN input is pulled high. The mono speaker (J9 connector) is also 

physically disconnected from the RO/MO+ output so that no sound is heard from the speaker while the headphones are 
inserted. 

When works as stereo mode make sure JP15, JP16, and JP17 are disconnected. 

4.3.15  USB device 

The SAM4E16 UDP port is compliant with the Universal Serial Bus (USB) rev 2.0 Full Speed device specification. J11 is 
a micro B-type receptacle for USB device. 

Both 27

Ω

 resistors R82 and R83 build up 90

 differential impedance together with the (embedded) 6

Ω

 output 

impedance of the SAM4E16 full speed channel drivers. 

R80 and R81 build up a divider bridge from VBUS +5V to implement plug-in detection (5V level gets lowered to a PIO 
compatible 3.3V level) through PC21.
