SLVUAM9 – December 2015 TPA3250D2EVM This user’s guide describes the operation of the evaluation module (TPA3250D2EVM) for the TPA3250D2 175-W Stereo/350-W mono peak power PurePath™ Ultra-HD Analog Input Pad Down Class-D Amplifier. The user’s guide also provides design information, which includes schematic, Bill of Material, and PCB layout. -
Page 2: Hardware Overview
TPA3250D2DDV operation with differential or single-ended input signals to the EVM with differential inputs yielding the optimal performance. TPA3250D2EVM is a complete 2Vrms analog input 175 W stereo/350 W mono peak power (90 W Stereo continuous into 8 Ω) amplifier ready for evaluation and excellent listening experience. -
Page 3: Tpa3250D2Evm Single-Ended And Differential Input
The TPA3250D2EVM supports both differential and single-ended inputs. For single-ended inputs, J4 and/or J19 jumpers are set to the SE position, so that the TPA3250D2EVM uses the NE5532 to convert the single-ended input signal to differential to properly drive the differential inputs of the TPA3250D2. The input RCA jack, J3, is used to provide INA and INB inputs and RCA jack J18 is used to provide INC and IND inputs with single-ended inputs. -

Using TPA3250D2EVM in Different Output Configurations www.ti.com Using TPA3250D2EVM in Different Output Configurations The TPA3250D2EVM can be configured for four different output operations. The 2.0 BTL configuration is the default set up of the TPA3250D2EVM described in Section 2.3. The remaining three configurations are 2.1 BTL plus two single-ended (SE) outputs, 0.1 PBTL output, and 4.0 single-ended (SE) outputs. -
Page 8: Single-Ended (Se) Output (4.0) Operation
Design the power supply with margins that can deliver the needed power. In low- frequency applications additional bulk capacitance may be needed. Replacing the bulk capacitors on the TPA3250D2EVM with 3300 µF or more capacitance may be necessary, depending on the power supply used. -
