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¡ªa

48-pin LQFP¡ªin turns enables a more compact set design.
