The IS31AP4912 is stereo headphone drivers designed to allow the removal of the output DC-blocking capacitors for reduced component count and cost. The IS31AP4912 is ideal for small portable electronics where size and cost are critical design parameters. The IS31AP4912 integrates click-and-pop suppression circuitry and thermal protect circuit. The gain of the amplifier is adjusted via external resistors. IS31AP4912 is available in UTQFN-12 (2mm × 2mm) packages. It operates from 2.7V to 5.5V over the temperature range of -40°C to +85°C.
