MAS6240 is a piezo driver IC designed to create a multi-tone sound based on a charge pump technology. It is a high efficiency, easy to use and low cost IC  perfect for battery driven equipment or other low voltage applications where a high sound pressure is needed.

MAS6240 can drive outputs up to 18 VP-P from single 3 V supply voltage. An input voltage amplification factor can be selected as 1, 2 or 3. The output can be single mode or differential mode.

The inductorless design causes significantly less disturbance to the surrounding circuits, making it an ideal choice Heart rate Monitors and other sensitive designs. Only four small value capacitors are needed in addition to a sound element. The use of small capacitors also makes this solution more reliable compared to an inductive solution using a heavy coil that can brake loose if the equipment is dropped.

MAS6240 can also be used in other applications. For  example as a white LED driver. At the same time it can be connected to a piezo sounder in a differential output configuration.
