Description

The RAA2S4704 is part of Renesas’ family of mixed-signal sensor ICs, designed for high-performance applications. It derives capacitance and conductance information from measured impedance, allowing for accurate assessments across a wide frequency range. This flexibility enables the measurement of both in-phase and quadrature-phase sensor components, tailored to specific environmental and application conditions.

The device features a configurable measurement scheme that maximizes the measurement rate based on the connected sensor or source. Measurements can be initiated on demand, using a predefined set of configurations. The acquired IQ data is transmitted via an SPI interface.

The RAA2S4704 offers excellent electromagnetic compatibility and a range of diagnostic features, making it ideal for demanding automotive environments. Its sensor inputs are protected against short circuits and designed to withstand overvoltage conditions typical in automotive applications.
