  • Page 3: Hardware Overview

    Hardware Overview The TPA3244EVM PurePath™ Ultra-HD evaluation module demonstrates the TPA3244DDW integrated circuit from Texas Instruments. The TPA3244DDW is a high-performance, high-power, class-D amplifier that enables true premium sound quality with high-efficiency class-D technology. It features an advance integrated feedback design and high-speed gate driver error correction (PurePath Ultra-HD), which enables ultra-low distortion across the audio band and superior audio quality.
  • Page 4: Tpa3244Evm Frequency Adjust

    For differential input operation, J4 or J19 jumpers are set to the DIFF position, and the TPA3244EVM uses the NE5532 to buffer the differential input signal to the differential inputs of the TPA3244. The input RCA jack, J3, is used to provide INA, RCA jack J14 provides INB, RCA jack J18 provides INC, and RCA jack J15 provides IND with differential inputs.
  • Page 5: Tpa3244Evm Clip Overtemperature And Fault Indicators

    TPA3244EVM Clip Overtemperature and Fault Indicators The TPA3244EVM is equipped with LED indicators that illuminate when the FAULT or CLIP_OTW pin goes low. See Table 2 and the TPA3244 data sheet (SLASEC6) for more details. Table 2. Fault and Clip Overtemperature Status FAULT CLIP_OTW Description Overtemperature (OTE) or overload (OLP) or undervoltage (UVP).

    • 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.
