Reference design for wireless optical comms
A new technology from Texas Instruments dramatically cuts the cost and complexity of bringing the high-speed datarates of optical networking to end users.
The TPA2010D1 is ideal for end equipments where high efficiency and board space are critical, such as cellphones, 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 (2.5W) while maximising the battery life in portable equipment using audio such as cellphones, smart phones and PDAs.
The 88% efficiency reached with a typical 8ohm speaker means that only a very small amount of power is wasted as heat and the low operation and shutdown current of 2.8mA and 0.5uA, 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.
The TPA2010D1 comes in a WCSP with lead and lead-free ball options and is available now from TI and its authorised distributors.
Suggested resale pricing in 1000-piece quantities is $0.55.
