This section provides an overview of the Texas Instruments (TI) TPA2012D2 NanoFree™ WCSP audio

amplifier evaluation module (TPA2012D2 EVM). It includes a brief description of the module and a list of

EVM specifications.

Supply voltage range, V

2.5 V to 5.5 V

Power supply current rating required 2.5 A

Continuous output power, P

: 4- Ω BTL, V

= 5 V 1.2 W (see note)

Audio input voltage, V

0 V to V

Minimum load impedance, Z

4 Ω

Note:

The TPA2012D2 in the RTJ package (QFN) is rated at 2.1 W/channel. The YZH package

(WCSP) is thermally limited to 1.2 W/channel on the EVM. For layouts with higher trace

density and additional copper, the maximum output power will be larger. See the data

sheet for device descriptions.
