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.

ROHM thermostat output temperature sensor ICs are available in the ultra-compact HVSOF5 package (1.6× 1.6mm t=0.6mm). Open Drain Active High operation ensures a temperature detection accuracy of +/-2.5ºC with no complicated circuitry required. Additional features include a power down function, low current consumption (75µA),and an analog temperature output pin, making them suitable for applications of all types, including overheat detection and temperature monitoring circuits.

ROHM's easy-to-use high efficiency H-bridge drivers for DC brush motors enable speed control while driving by performing switching operations of the output MOSFETs via PWM conversion of speed setting voltage inputs.

Multiple protection circuits and careful layout design ensures high reliability, while PWM drive reduces power consumption. The result is the optimal solution for virtually any application.
