Overview

Description

Smart Analog IC502 has a built-in high-speed instrument amplifier with comparator and D/A converter. It is suitable for home appliances that require motor control.

The RAA730502 is a monolithic programmable analog IC with a range of on-chip circuits such as high-speed instrumentation amplifiers with comparators, D/A converters, and a temperature sensor, allowing the RAA730502 to be used as an analog front-end device for sensing current in motor control applications. The RAA730502 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 RAA730502—a 48-pin LQFP—in turns enables a more compact set design.
