Overview
The TAS3251DKQR is a Texas Instruments Class-D audio amplifier integrated circuit housed in a 56-HSSOP package. It supports mono or stereo output configurations with a supply voltage range of 12V to 38V. Maximum power output reaches 350W into 2 ohms, 220W into 3 ohms, and 175W into 4 ohms for single-channel operation. The device operates within an ambient temperature range of 0°C to 70°C.
Feature Summary
- Ultra-HD digital input architecture with advanced DSP processing capabilities
- PurePath technology integration for high-fidelity audio reproduction
- Supports both mono and stereo channel configurations
Applications
- High-power home theater systems
- Professional audio amplification equipment
- Active loudspeaker designs requiring digital input interfaces
Procurement Notes
Verify the specific suffix DKQR against the official datasheet to confirm the tape and reel packaging configuration. Ensure the design accounts for the 56-pin PowerBSSOP thermal requirements and the specified operating temperature limits. Confirm RoHS3 compliance status matches current manufacturing standards before finalizing procurement orders.
Selection Notes
Select this component when a digital-input Class-D amplifier with integrated DSP is required for high-power applications. Compare against analog-input alternatives like the TPA3251 if digital interface compatibility is not needed. Evaluate thermal management solutions suitable for the HSSOP-56 package given the high power dissipation levels at maximum output.
Part Context
This part belongs to the TAS3251 series of Ultra-HD digital-input amplifiers. It is distinct from the TPA3251 family, which utilizes analog inputs. The TAS3251DKQR specifically denotes the reel-packaged version of the standard TAS3251 device, designed for automated surface-mount assembly processes.
Replacement Considerations
The TPA3251D2 serves as a functional alternative but requires analog input signals instead of digital. For direct pin-compatible replacements, verify availability of other TAS3251 variants with different packaging options such as tube formats.
