RAA730300
Monolithic Programmable Analog IC
Overview

Rev.1.10
May. 31, 2014
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.
