TPA3251D2DDVR is a Texas Instruments audio power amplifiers device in the HTSSOP-44 (DDV) package. The manufacturer currently lists this exact ordering code as ACTIVE. Component selection must use its specified electrical conditions and suffix, rather than extrapolating a family feature to every ordering variant.
Manufacturer-verified electrical and ordering conditions
| Selection fact | Verified value | Applicable operating/test condition |
|---|---|---|
| Amplifier | Class-D stereo/mono | smart audio analog input architecture |
| Stereo Reference | 175 W | conditioned stereo reference rating; not all loads/rails |
| Mono Reference | 350 W | reference mono power, requires matching loading and thermal setup |
| Pvdd | 12 to 36 V | TI feature table 12–36 V headline operating region; recommended PVDD table lists 38 V absolute upper recommended maximum. Actual output power is load, THD+N and thermal-dependent. |
| Ambient | 0 to +70 °C | manufacturer exact orderable commercial ambient |
| Exact Orderable Package | HTSSOP-44 (DDV) 44 pins | Exact TI product orderable listing Package / Pins HTSSOP (DDV) / 44 Operating temperature range (°C) 0 to 70 Package qty / Carrier 2,000 / LARGE T&R Features for the TPA3251 Differential Analog Inputs Total Output Power at 10 |

Audio power ratings depend on loads and distortion
The published 175 W stereo and 350 W mono headlines are specific Class-D configuration reference results, not simultaneously guaranteed power into any speaker. The source datasheet identifies those output ratings at particular 10% THD+N operating conditions; a design with lower distortion targets, different speaker impedance or limited heatsinking will have a different practical power envelope. Avoid using these numbers as an unconditional customer-facing promise.
The TI datasheet describes a 12–36 V power-supply operating headline and its detailed recommended PVDD_x table lists an upper maximum of 38 V. This is not permission to disregard thermal management or to promise the headline output at 38 V. The DDV 44-pin thermally enhanced package needs an appropriate heat-removal interface. The exact commercial orderable is specified for a 0–70 °C ambient environment; do not transfer automotive-grade temperature limits from unrelated amplifiers.
Exact-package sourcing and verification
This listing is for the precise TI orderable TPA3251D2DDVR, in HTSSOP-44 (DDV). It is an RFQ-only product record: no displayed price, unverified stock, future lead time or guaranteed substitute is implied. Provide the requested quantity and lot/date-code requirements for sourcing verification.
