ROHM offers the most efficient, coolest class D speaker mplifiers on the market. Optimized for high performance compact equipment with limited space for adequate heat dissipation, ROHM Class D amps provide the ideal solution in a space efficient, energy saving design without sacrificing sound quality.
■ubstantial energy savings for speaker amplifiers
Cutting-edge BiCDMOS processes are used to minimize the output transistor ON-resistance and the wiring resistance, resulting in an industry-best efficiency of 91% (10W + 10W output, 8Ω load).
■No heat sinks or output LC filters required
ROHM's 2.5W BD5460GUL and BD5461GUL utilize a unique filterless modulation method that eliminates the need for large, expensive output LC filters. Only three external parts are required, realizing significant parts and space savings.
Energy-saving Class D operation, combined with circuit optimization, has resulted in low 6.5mW power consumption for longer battery life, making ROHM's Hi-fi digital input Class D headphone amps ideal for portable audio devices of all types.
A highly conductive polymer is used for lower ESR and the industry' s highest capacitance ‒ up to 100µF ‒ all in a thin (1.1mm), compact 3216(1206)-sized package.
Stable optical output characteristics and high breakdown resistance are just two characteristics of ROHM's original element structure. In addition, a thin, high heat-dissipating frame package is used, providing the ideal solution for compact equipment.
RPMS2□□1-H19 series
The ultra-compact package can be mounted in an area as small as 9mm2,greatly increasing substrate design freedom. Additional features include an original lens design that greatly reduces malfunctions and low power consumption for longer battery life.
