Overview
The TAS5110ADADG4 is a true-digital audio amplifier power stage from Texas Instruments, housed in a 32-pin PowerPAD HTSSOP package. It delivers up to 50 W RMS into a 6-ohm load at 10% THD and 40 W RMS at 0.1% THD. The device operates with a 3.3-V digital interface and requires a high-voltage supply between 16.5 V and 26.5 V. It incorporates Equibit technology for efficiency exceeding 90%. Built-in protections include overcurrent, overtemperature, and undervoltage lockout.
Feature Summary
- Integrates an internal CMOS H-bridge controlled by a 3.3-V mono PWM input signal.
- Includes self-protecting design features such as short-circuit, overtemperature, and undervoltage protection.
- Features two on-chip low-dropout voltage regulators dedicated to half-bridge gate drivers.
- Utilizes bootstrapped gate drive circuitry to minimize external high-voltage power supply requirements.
Applications
- DVD Receivers
- Home Theater Systems
- Mini/Micro Component Audio Systems
- Internet Music Appliances
- Car Audio Amplifiers and Head Units
Procurement Notes
Verify the specific ordering suffix 'G4' against current Texas Instruments documentation to confirm lead-free status and RoHS compliance. Confirm that the DAD package designation matches the required 32-pin thermally enhanced surface-mount footprint. Ensure the procurement channel provides valid production data sheets, as availability status may vary.
Selection Notes
Select this component when designing systems requiring high-efficiency digital amplification with integrated power stages. It must be paired with a compatible digital audio PWM processor, such as the TAS50xx series, to function correctly. Designers must account for thermal management strategies suitable for the PowerPAD package to achieve maximum rated output power.
Part Context
This part belongs to the TAS5110A family of True Digital Audio Amplifiers (TDAA). It utilizes TI's PurePath Digital and Equibit technologies to provide high-power audio amplification. The device is designed to work in conjunction with digital processors to deliver stereo or multi-channel audio solutions with minimal external components.
Replacement Considerations
TAS5110ADAD: Non-RoHS compliant version of the same functional device. TAS5110ADADR: Tape and reel packaging variant. TAS5110ADADRG4: Lead-free, RoHS-compliant tape and reel variant.
