Smart Analog IC300 has a built-in configurable amplifier, low-pass filter and high-pass filter. It is suitable for battery-operated home appliances, industrial applications and healthcare equipment.

The RAA730300 is a monolithic programmable analog IC that supports low voltages and features a range of on-chip circuits such as configurable amplifiers, general-purpose operational amplifiers, D/A converters, and a temperature sensor, allowing the RAA730300 to be used as an analog front-end device for processing minute sensor signals. The RAA730300 uses a Serial Peripheral Interface (SPI) to allow external devices to control each on-chip circuit, enabling a more compact package and a reduction in the number of control pins. The compact package used by the RAA730300—a 48-pin LQFP—in turns enables a more compact set design.
