The thrust for higher power and better sound quality in small digital packages, especially on flat panel displays, has pushed engineers in developing Class D amplifier technology onto a small chip-sized IC. Folks at Sanyo has announced the development of a high performance and efficiency hybrid IC promises to deliver 600 watts of low distortion’s Class D digital amplifying.
Digital amp is not a stranger to space-constrained electronic devices; diminutive in size, it also runs cool and doesn’t run up your power bills. Manufactures have came out with Class D “Icepower” digital amps that are matching the performance of many audiophile components without the need of giant heatsinks like Class A amplifier. Conveniently, with little twist in driver circuitry, it fits nicely onto a flat panel TVs.
The development of Sanyo digital amp covering a trio of hybrid IC chips with capability to deliver Class D power of 100w, 200w and 300w with dual-channel driven into 8 ohm impendence. The 300w model is said to have 90% power conversion efficiency. The product is also compatible with HD audio playback due to a higher Pulse width modulation carrier frequency of 768khz.
Shipment of engineering samples is said to begin from March 2009. It will cost you 1,000 yen ($10.50) each.
