Texas Instruments provides a recommended layout and routing guide in the DDC118IRTCR Evaluation Module User's Guide (SLAU575). It's essential to follow this guide to ensure optimal performance and minimize noise coupling.
To optimize the DDC118IRTCR for low noise performance, ensure that the input signal is properly filtered, use a low-noise voltage regulator, and minimize the distance between the DDC118IRTCR and the voltage regulator. Additionally, use a solid ground plane and avoid routing digital signals near the analog inputs.
The maximum input signal amplitude that the DDC118IRTCR can handle is ±1.5 V, but it's recommended to keep the input signal amplitude below ±1 V to ensure optimal performance and linearity.
The DDC118IRTCR does not require calibration. It has an internal calibration mechanism that ensures accurate performance over the entire operating temperature range. However, it's essential to follow the recommended layout and routing guidelines to ensure optimal performance.
The typical settling time of the DDC118IRTCR is around 10 μs, but it can vary depending on the input signal frequency and amplitude. It's essential to consult the datasheet and application notes for more information on settling time and how to optimize it for specific applications.
