TAS5121IDKDR

Overview

The TAS5121IDKDR is a 100-W mono digital amplifier power stage manufactured by Texas Instruments. It utilizes a 36-pin HSSOP package and operates within a temperature range of -40°C to 85°C. The device requires a supply voltage between 10.8V and 13.2V. Key electrical parameters include a nominal bandwidth of 20 kHz, a harmonic distortion of 10%, and two channels with one functional unit.

Feature Summary

• Integrated digital amplifier power stage architecture
• Mono channel configuration for single speaker output
• Designed for operation within specified automotive-grade temperature ranges

Applications

• Automotive audio systems
• High-power mono speaker amplification
• Digital audio processing stages

Procurement Notes

Verify the specific package type (HSSOP) and pin count (36) against your PCB footprint requirements. Confirm that the supply voltage constraints (10.8V to 13.2V) align with your system design. Ensure thermal management solutions are adequate for the 100-W output capability in the intended operating environment.

Selection Notes

Select this component when a high-power mono digital amplifier solution is required. Consider the 36-pin HSSOP package size for layout constraints. Verify compatibility with the required 10.8V to 13.2V supply voltage range before integration into the final audio system design.

Part Context

This part belongs to the Texas Instruments audio amplifier family, specifically designed for digital power stages. It is distinct from other TI audio components like the PCM5121PW DAC or THS4121ID differential amplifier due to its specific mono amplifier function and higher power output capabilities.

Replacement Considerations

The TAS5121IDKDR E4 is a verified equivalent variant with identical functionality but potentially different lead-free compliance markings. No other direct substitutes are confirmed in the provided documentation.
