HPA00194DGNR

Overview

The HPA00194DGNR is a mono analog input Class-AB audio amplifier manufactured by Texas Instruments. It delivers 1.25W of output power and features a 90dB Power Supply Rejection Ratio (PSRR). The device is housed in an 8-pin MSOP-PowerPad package, designed for compact audio applications requiring efficient power management and high-quality sound reproduction.

Feature Summary

• Class-AB topology for low distortion audio amplification
• High PSRR for noise reduction from power supply lines
• Compact MSOP-PowerPad-8 package for space-constrained designs

Applications

• Portable audio devices
• Mobile phone speaker systems
• Small form-factor multimedia equipment

Procurement Notes

Verify the exact part number suffix to ensure compatibility with specific packaging or temperature grades. Confirm that the MSOP-PowerPad-8 footprint matches your PCB layout requirements. Check for restricted availability status as indicated by distributors. Ensure thermal management solutions are adequate for the 1.25W output capability in your enclosure design.

Selection Notes

Select this component when a single-channel audio solution is required with moderate power output. The Class-AB architecture offers a balance between efficiency and linearity suitable for general-purpose audio. Consider the 8-pin MSOP package size against available board real estate. Verify that the 90dB PSRR meets the noise immunity requirements of your power supply environment.

Part Context

This part belongs to the Texas Instruments HPA series of audio amplifiers. These components are designed for consumer electronics where size and power efficiency are critical. The HPA series typically integrates protection features and requires minimal external components for basic operation.

Replacement Considerations

Consult official TI substitution guides for compatible alternatives within the HPA family. Ensure any replacement maintains the same pinout and package dimensions to avoid PCB redesign.
