TI Debuts Industry's Smallest Mono Filter-Free Class-D Audio Power Amp

2/13/2004 - Enabling wireless and personal digital assistant (PDA) designers to conserve board space while gaining efficiency, Texas Instruments Incorporated (TI) (NYSE: TXN) announced the smallest and highest performance filter-free Class-D mono audio power amplifier in the market. This 2.5-W device is available in TI's state-of-the-art Wafer Chip Scale Package (WCSP), which measures only 1.45mm by 1.45mm and comes in lead and lead-free ball options. The TPA2010D1 is ideal for end equipments where high efficiency and board space are critical, such as cell phones, smart phones and PDAs.

"The TPA2010D1 squeezes all the benefits of a high-efficiency, filter-free Class-D audio power amplifier into a minuscule package solution," said Gregg Lowe, senior vice president of TI´s High Performance Analog division. "Providing a new WCSP package option for TI´s Class-D audio power amplifiers allows us to further strengthen our relationship with key wireless and PDA manufacturers."

The TPA2010D1 is designed to use a very small amount of board real-estate and provide a large amount of output power (2.5-W) while maximizing the battery life in portable equipment using audio such as cell phones, smart phones and PDAs. The 88 percent efficiency reached with a typical 8-Ohm speaker means that only a very small amount of power is wasted as heat and the low operation and shutdown current of 2.8-mA and 0.5-uA, respectively, saves valuable battery charge. Furthermore, the fully-differential architecture virtually removes effects like "RF-rectification:" a common issue in TDMA and GSM mobile phones. The device needs only three external components for correct operation and was designed for maximum system flexibility.
