Overview
The TPA2038D1YFFT is a single-channel mono Class-D audio amplifier manufactured by Texas Instruments. It operates on a single power supply ranging from 2.5 V to 5.5 V and delivers up to 3.2 W of output power into a 4-ohm load. The device features variable gain control and includes integrated protection mechanisms such as short-circuit and thermal shutdown. It is housed in a compact 9-pin DSBGA package suitable for surface-mount applications.
Feature Summary
- Variable gain configuration allows flexible signal amplification levels
- Integrated short-circuit and thermal protection ensures operational reliability
- Supports differential input signals for improved noise immunity
Applications
- Portable media players
- Mobile handsets
- Personal digital assistants
Procurement Notes
Verify the specific suffix YFFT against the official datasheet to confirm the tape-and-reel packaging format. Ensure the design supports the required voltage range and thermal dissipation for the DSBGA-9 package. Confirm RoHS compliance status with the manufacturer before finalizing procurement orders.
Selection Notes
Select this component when variable gain adjustment is required rather than fixed gain alternatives like the TPA2039D1. Consider the DSBGA-9 footprint constraints and ensure the application environment stays within the -40°C to +85°C operating temperature range. Verify that the single-supply architecture aligns with the system power budget.
Part Context
This part belongs to the TPA2038D1 series of high-efficiency Class-D audio amplifiers. It is designed for battery-powered portable electronics where space and power efficiency are critical. The series offers a balance of performance and integration, distinguishing it from higher-power or multi-channel variants in the broader audio amplifier portfolio.
Replacement Considerations
The TPA2038D1YFFR serves as a direct replacement variant differing only in packaging format (reel versus cut tape). Other family members like the TPA2037D1 offer fixed gain instead of variable gain.
