The Texas Instruments TPA2010D1 is a 2.5-W high-efficiency, filter-free Class-D audio power amplifier designed for portable applications. It features an optimized PWM output stage that eliminates the need for an LC output filter, contributing to its compact design and reduced component count. With an efficiency of up to 88% when driving an 8-Ω speaker at 400 mW, the TPA2010D1 maximizes battery life and minimizes heat generation.
This amplifier operates from a wide supply voltage range of 2.5 V to 5.5 V, eliminating the need for a separate voltage regulator. It boasts a low quiescent current of 2.8 mA and a shutdown current of just 0.5 µA, further enhancing power efficiency. The device also features improved PSRR of -75 dB and CMRR, reducing susceptibility to noise and eliminating the need for bypass capacitors.
The TPA2010D1 is housed in a small 1.45 mm x 1.45 mm die-size ball grid array (DSBGA) package, making it ideal for space-constrained designs. Its fast start-up time of 1 ms with minimal pop makes it suitable for applications like cellular handsets and personal navigation devices where quick audio response is critical.
The TPA2010D1 operates from 2.5V to 5.5V for both power stage and analog supplies.
The TPA2010D1 is available in a DSBGA (YZF) package measuring 1.45mm x 1.45mm.
The operating temperature range is -40°C to 85°C.
The TPA2010D1 delivers 2.5W output power into a 4Ω load.
Typical THD+N is 0.18% at 1kHz.
Efficiency is 88% at 400mW into an 8Ω speaker and 80% at 100mW.
Quiescent current is 2.8mA typical.
