The Texas Instruments TPA2031D1YZFR is a high-efficiency, filter-free Class-D audio power amplifier. It delivers up to 2.5W of output power into a 4Ω load, operating from an analog supply voltage range of 2.5V to 5.5V. This amplifier features a typical quiescent current of 2.8mA and a shutdown current of 0.5μA, contributing to maximum battery life and minimal heat generation.
Designed for applications requiring compact solutions, the TPA2031D1YZFR comes in a 1.45mm x 1.45mm wafer chip scale package (WCSP). It requires only three external components, reducing board space and simplifying design. The amplifier boasts an efficiency of 88% at 400mW with an 8Ω speaker, and features improved PSRR of -75dB and a wide supply voltage range, eliminating the need for a voltage regulator.
Key electrical characteristics include a THD + N of 0.18% at 1kHz. The device has a start-up time of 32ms, which helps eliminate CODEC click/pop noise. Its optimized PWM output stage eliminates the need for an LC output filter, and a fully differential design reduces RF rectification and eliminates the bypass capacitor. The improved CMRR further eliminates two input coupling capacitors.
Applications for the TPA2031D1YZFR include wireless or cellular handsets and PDAs. Its pin-to-pin compatibility with the TPA2010D1 makes it suitable for upgrades. The operating temperature range is -40°C to 85°C.
