Basic amp simplifies audio circuitry
A miniature audio amplifier from Rohm should simplify the design, reduce the board space and minimise the power consumption of audio driver circuitry in battery-powered applications.
A miniature audio amplifier from Rohm should simplify the design, reduce the board space and minimise the power consumption of the loudspeaker and headphone driver circuitry in battery-powered applications Ideally suited to mobile telephones, PDAs, handheld games and other portable devices requiring audio output, the BH7823AFVM is a mono audio power amplifier offering a high-power, 500mW/BTL output capable of driving loads of 4, 8 and 12ohm

Rohm has launched a device that will simplify the design of mobile phones requiring full colour backlights by delivering the increased voltages and driving functionality demanded by white LEDs.
The device offers a low typical current consumption of just 3mA and features a 'suspend' function that reduces consumption to zero when the amplifier does not need to be active.
The BH7823AFVM can accommodate a wide operating voltage range of between 2.8 and 5.5V, features a built-in 'antipop' circuit and offers a very low typical distortion of 0.2%.
A thermal shutdown function protects the amplifier in the event of an overtemperature condition.
Supplied in a miniature MSOP8 plastic mould package measuring just 2.9 x 2.8 x 0.9mm, the BH7823AFVM will operate at temperatures between -20 and +70C and has a maximum power dissipation of 370mW at 25C.
