Smart Analog IC500 has a built-in configurable amplifier, synchronous detection amplifier, D/A converter, low-pass filter and high-pass filter. It is suitable for home appliances, industrial applications and healthcare equipment. The RAA730500 is a monolithic programmable analog IC with a range of on-chip circuits such as configurable amplifiers, a synchronous detection amplifier, a general-purpose operational amplifier, D/A converters, and a temperature sensor, allowing the RAA730500 to be used as an analog front-end device for processing minute sensor signals. The RAA730500 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 RAA730500—a 48-pin LQFP—in turns enables a more compact set design.
