- Built-in diagnostics for safety-critical applications (vs MAX11254)
Design Notes
The AD4130-4BCPZ operates from a single analog supply of 1.71 V to 3.6 V. Use a low-noise LDO such as the ADP150 to provide a clean supply. Decouple AVDD and DVDD with 0.1 μF and 10 μF capacitors placed close to the pins. The reference inputs should be decoupled with 0.1 μF and 1 μF capacitors to ensure stable operation.
For optimal performance, use a solid ground plane and separate analog and digital ground planes if necessary. Place the ADC close to the sensor to minimize trace length. Route analog inputs away from digital signals to reduce noise coupling. Use a 4-layer PCB with dedicated power and ground planes for best results.
Avoid exceeding the absolute maximum ratings on any pin. Ensure the SPI lines are not driven above VIO. The exposed pad (EP) must be soldered to the ground plane for thermal and electrical performance. Do not leave unused inputs floating; connect them to AVSS or configure them as outputs. Use the internal temperature sensor for diagnostics if needed.
