TPA2038D1YFFR Description

Short technical summary and product information.

The TPA2038D1YFFR from Texas Instruments is a high-efficiency, filter-free Class-D audio power amplifier designed for mono applications. It offers a selectable gain feature, allowing users to choose between 6 dB and 12 dB.

 

This amplifier can deliver up to 3.2 W into a 4 ℆ load with 10% THD+N from a 5 V supply. It also provides 1.4 W into 8 ℆ at 1% THD+N and 2.5 W into 4 ℆ at 1% THD+N. The device operates with an analog supply voltage range of 2.5 V to 5.2 V and a power stage supply range of 2.5 V to 5.5 V.

 

Key features include low quiescent current of 1.5 mA, low output noise of 20 µV, and 95% efficiency. It also incorporates auto-recovering short-circuit protection and thermal-overload protection. The TPA2038D1YFFR is available in a compact 9-ball, 1.21 mm x 1.16 mm, 0.4 mm pitch WCSP package, suitable for space-constrained designs.

 

Applications include wireless or cellular handsets, PDAs, portable navigation devices, and general portable audio devices.
