Frequently Asked Questions
What is the maximum output power of the TPA3245DDVR?
The TPA3245DDVR delivers up to 115 W per channel in stereo (2-channel BTL) mode and up to 230 W in mono (parallel BTL) mode when powered from a 31.5 V supply into a 4 Ω load, making it one of the highest-power single-chip Class-D amplifiers available.
What supply voltage range does the TPA3245DDVR support?
The TPA3245DDVR operates over a wide supply voltage range of 12 V to 31.5 V, giving designers flexibility to use standard 24 V or 12 V rails in home audio, professional audio, and automotive applications without additional regulation.
What package does the TPA3245DDVR use, and what are its key dimensions?
The TPA3245DDVR is housed in a 44-pin HTSSOP (R-PDSO-G44) small-outline package. The exposed thermal pad on the underside facilitates efficient heat dissipation, helping the device maintain full output power at elevated ambient temperatures.
Can the TPA3245DDVR be used as a drop-in replacement for similar Class-D amplifiers?
While the TPA3245DDVR is pin-compatible and functionally similar to several Texas Instruments Class-D amplifiers such as the TPA3244, direct substitution depends on supply voltage, gain settings, and PCB layout. Always verify the datasheet specifications and application schematic before replacing components.
Where can I buy the TPA3245DDVR and what is the price?
The TPA3245DDVR is available from authorised distributors and on FindMyChip.com from approximately $2.91 per unit. Stock is available worldwide with standard and expedited shipping options to support production and prototype quantities.
