Proprietary circuit configuration is utilized for the lowest power consumption and distortion in the industry: 2mA and 0.006%, respectively. This 2mA represents 50% less power consumption compared with conventional headphone amps without an output coupling capacitor under similar conditions.

The BU7150NUV headphone amp features a wide operating voltage range (0.93V to 3.5V), making operation possible with even one or two batteries. In addition, a step-up circuit is not required, reducing power consumption for longer battery life.

A copper frame mitigates the effects of magnetic fields (US6H23), resulting in superior audio quality, while low ON-resistance improves attenuation characteristics. In addition, a dual-type model is available that decreases the number of external components required along with mounting area.

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.

A conductive polymer with high conductivity is used for significantly lower ESR. Available in the 3216 size with a thickness of only 0.9mm. Features include the largest capacitances in the industry.

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.

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.
