Smart Analog IC301 has a built-in instrument amplifier and D/A converter. It is suitable for battery-operated home appliances, industrial applications and healthcare equipment.

The RAA730301 is a monolithic programmable analog IC that supports low voltages and features a range of on-chip circuits such as an instrumentation amplifier, a D/A converter, and a temperature sensor, allowing the RAA730301 to be used as an analog front-end device for processing minute sensor signals. The RAA730301 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 RAA730301—a 48-pin LQFP—in turns enables a more compact set design.
