Overview
The TPA6204A1DRB is a single-channel mono Class-AB audio amplifier manufactured by Texas Instruments. It delivers 1.7 W of output power into an 8-ohm load with a total harmonic distortion plus noise of 0.03%. The device operates on a single supply voltage ranging from 2.5 V to 5.5 V and draws a typical quiescent current of 4 mA. It features fully differential inputs and outputs, housed in an 8-pin SON package. The component supports an operating temperature range from -40°C to +85°C.
Feature Summary
- Fully differential input and output architecture for improved noise rejection
- Integrated pop-and-click suppression circuitry
- Thermal shutdown protection for enhanced reliability
Applications
- Portable media players
- Mobile phones
- Personal digital assistants
Procurement Notes
Verify the specific suffix DRB corresponds to the tube packaging configuration as indicated in distributor specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Cross-reference the exact part number against the latest datasheet revision to confirm pinout and electrical characteristics match design requirements.
Selection Notes
Select this component when a single-ended to fully differential conversion is required within a compact footprint. The 8-SON package facilitates space-constrained designs compared to larger packages. Consider the 4 mA quiescent current for battery-powered applications where low standby consumption is critical. Evaluate the 1.7 W power capability against the specific speaker impedance and desired volume levels.
Part Context
This device belongs to the TPA6204A1 series of audio amplifiers. It shares the same core functionality and package type with variants such as the TPA6204A1DRBT, which differs primarily in reel packaging. Related models like the TPA6203A1 and TPA6205A1 offer similar Class-AB performance but may vary in output power or quiescent current specifications.
Replacement Considerations
The TPA6204A1DRBT serves as a direct functional substitute with identical electrical characteristics, differing only in tape-and-reel packaging instead of tubes.
