Texas Instruments provides a recommended layout and routing guide in the ADS61B23IRHBR evaluation module documentation. It's essential to follow these guidelines to minimize noise, ensure signal integrity, and achieve optimal performance.
To optimize the analog input circuitry, use a low-pass filter to remove high-frequency noise, ensure a stable voltage reference, and use a buffer amplifier if necessary. Additionally, consider the input impedance, common-mode voltage, and differential voltage ranges to ensure proper operation.
The ADS61B23IRHBR outputs data in a serial format. Use a FIFO or a buffer to handle the data stream, and consider using a digital signal processor (DSP) or a microcontroller with a built-in ADC interface to process the data. Ensure proper synchronization and data alignment to avoid errors.
Calibration involves adjusting the offset and gain of the ADC. Use the built-in calibration registers or an external calibration circuit to adjust the offset and gain. Refer to the datasheet and application notes for specific calibration procedures and equations.
The ADS61B23IRHBR has a maximum junction temperature of 150°C. Ensure proper heat sinking, use a thermal pad or heat sink, and maintain a reasonable ambient temperature to prevent overheating. Monitor the device's temperature and adjust the operating conditions accordingly.
