SE (4.0) output channel configurations. The NE5532 is a high-performance audio op amp designed to allow TPA3244DDW operation with differential or single-ended input signals to the EVM with differential inputs yielding the optimal performance. The TPA3244EVM is a complete 2-V analog input 2 ×... -
Page 4: Tpa3244Evm Frequency Adjust
The TPA3244EVM supports both differential and single-ended inputs. For single-ended inputs, J4 or J19 jumpers are set to the SE position, so that the TPA3244EVM uses the NE5532 to convert the single- ended input signal to differential to properly drive the differential inputs of the TPA3244. The input RCA jack, J3, is used to provide INA inputs and RCA jack J14 is used to provide INB inputs. -

Page 10: Using The Tpa3244Evm In Different Output Configurations
Using the TPA3244EVM in Different Output Configurations www.ti.com Using the TPA3244EVM in Different Output Configurations The TPA3244EVM can be configured for four different output operations. The 2.0 BTL configuration is the default setup of the TPA3244EVM 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 11 All manuals and user guides at all-guidesbox.com Using the TPA3244EVM in Different Output Configurations www.ti.com • Connect right (stereo) channel input to female RCA jack input D (BLACK) for OUTD speaker. • For single-ended subwoofer (mono) input, connect RCA male jack to female RCA jack input A/AB (RED) and set J4 jumper positions to SE.

Page 13: Single-Ended (Se) Output (4.0) Operation
• Connect input to female RCA jack input D (BLACK) for OUTD speaker. NOTE: The performance of the TPA3244EVM/TPA3244 is dependent on the power supply. 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 TPA3244EVM with more capacitance may be necessary, depending on the power supply used. -
Page 14: Optional Inductors
Optional Inductors The TPA3244EVM includes component pads for optional output inductors L8 and L9. These pads fit Coilcraft inductors UA8013-AL (7 µH) and UA8014-AL (10 µH). These dual-core inductors provide extremely high performance in a small footprint to help shrink the solution size and cost. If using L8 and L9, make sure to de-solder L2, L3, L4, and L5 first. -
