Industry's First Inductorless, Class G Speaker Amplifier Doubles Output Power and Increases Battery Life Maxim Integrated Products introduces the MAX9730, a 2.4W, single-supply, mono, Class G speaker amplifier. The MAX9730's Class G architecture and integrated charge-pump power supply enable this device to deliver two times more output power than conventional Class AB or Class D speaker amplifiers provide from a lithium-ion (Li+) battery. The charge pump can deliver up to 500mA over a 2.7V to 5.5V supply-voltage range, guaranteeing up to 2.4W into an 8Ohm load from a 3.3V supply. The MAX9730 significantly reduces the size and cost of the total solution by eliminating the boost converter and large inductor commonly needed to achieve the same performance—this makes it ideal for cellular phones, notebook computers, and other portable applications in which board space is limited.

Lattice Releases Reference Design For GPON Burst Mode Receiver Lattice Semiconductor Corporation today announced the availability of its PURESPEED™ I/O Burst Mode Receiver (BMR) FPGA Reference Design for Gigabit Passive Optical Networks (GPON). This reference design uses Lattice's unique Adaptive Input Logic (AIL) block found on its LatticeSC™ FPGAs and LatticeSCM™ FPGAs (collectively, the LatticeSC/M family) to rapidly establish stable clock to data timing relationships within the fast lock times specified in the GPON ITU-T G.984.1 specification, which requires the Optical Line Termination (OLT) to lock to incoming data within 50 bit times.
