ADS7038IRTET datasheet by Texas Instruments

ADS7038IRTET Frequently Asked Questions (FAQs)

• What is the recommended layout and routing for the ADS7038IRTET?
  Texas Instruments provides a recommended layout and routing guide in the ADS7038 application note (SLAA745). It's essential to follow this guide to ensure optimal performance and minimize noise coupling.
• How do I calibrate the ADS7038IRTET?
  The ADS7038IRTET does not require calibration. It has an internal calibration circuit that ensures accurate performance over temperature and voltage. However, if you need to perform system-level calibration, you can use the offset and gain adjustment registers to trim the output.
• What is the maximum sampling rate I can achieve with the ADS7038IRTET?
  The ADS7038IRTET has a maximum sampling rate of 1 MSPS. However, the actual sampling rate may be limited by the system's clock frequency, analog input bandwidth, and digital interface throughput.
• Can I use the ADS7038IRTET with an external reference voltage?
  Yes, the ADS7038IRTET has a REF_IN pin that allows you to connect an external reference voltage. This can be useful if you need to match the ADC's reference voltage to a specific system requirement or to improve accuracy.
• How do I handle the digital output data from the ADS7038IRTET?
  The ADS7038IRTET outputs 12-bit digital data in a serial format. You'll need to use a microcontroller or FPGA to receive and process the data. Texas Instruments provides example code and interface guidelines in the ADS7038 datasheet and application notes.
