TAS5825P Evaluation Module
2.1 Features
The EVM has the following features:
• TAS5825P Hybrid-Pro algorithm for audio envelope tracking
• Integrates LM5155 boost to provide customer system design reference
• Default system configuration: 5V battery input, boost to max 16 V power rail based on audio envelope
tracking
• Flexible TAS5825P Hybrid-Pro output (HPFB pin) to customer system board capability
• Demonstration, evaluation and development environment via the PurePath Console 3 software (GUI)
2.2 Functions
The TAS5825PEVM provides USB control via PurePath Control Console 3 (PPC3). The digital audio data
input to the TAS5825PEVM is selectable from USB audio, optical SPDIF, PSIA (external I2S) and 3.5 mm
analog jack.
2.3 Detailed Operations
The TAS5825PEVM has three different optional audio sources:
1. If XMOS is selected manually by toggling the S1 switch, the Windows Media Player can be used to
stream audio.
2. If SPDIF is selected manually by toggling the S1 switch, a DVD player with a optical SPDIF cable can
be used to provide audio stream.
3. If external digital audio source such as Programmable Serial Interface Adapter (PSIA) from Audio
Precision, jumpers (J13, J11, J14) can be used to insert external I2S signals.
Both 3.3 V and 1.8 V DVDD and IOVDD are supported with TAS5825PEVM. Jumper (J15) can be used to
select accordingly based on requirement.
TAS5825PEVM provides optional onboard LM5155 boost Hybrid-Pro evaluation or external customer
system boost with Hybrid-Pro feedback (HPFB pin) control:
1. Onboard LM5155 boost Hybrid-Pro evaluation
• 5 V battery power input through J1 and J2. Bypass external PVDD through DNP J22
• TAS5825P PVDD is from LM5155 boost output: J10 - IN, J22 - OUT
• TAS5825P HPFB pin routes to LM5155 FB pin: J3 - IN, J4 - OUT
2. External customer system boost with Hybrid-Pro feedback (HPFB pin) control
• TAS5825P HPFB pin routes for external customer system boost FB control through TP3 FB and
TP13 GND: J3 - OUT, J4 - OUT
• Customer system boost output for TAS5825P PVDD through J21 PVDD and J23 GND: J10 - OUT,
J22 - IN
The USB connection is also used to provide I2C communications with TAS5825P on the EVM. The Pure
Path Console 3 (PPC3) is the software tool which can initialize and operate this EVM.
