ADS7958SDBTR Frequently Asked Questions (FAQs)

• What is the recommended layout and routing for the ADS7958SDBTR to achieve optimal performance?
  Texas Instruments provides a layout and routing guide in the ADS7958SDBTR evaluation module documentation, which includes recommendations for PCB layout, component placement, and routing to minimize noise and ensure optimal performance.
• How do I calibrate the ADS7958SDBTR to achieve the highest accuracy?
  The ADS7958SDBTR has an internal calibration circuit that can be used to calibrate the device. The calibration process involves applying a known input voltage and then using the CAL pin to store the calibration data. The device can also be calibrated using an external calibration circuit. Refer to the datasheet and application notes for more details.
• What is the maximum sampling rate that can be achieved with the ADS7958SDBTR?
  The maximum sampling rate of the ADS7958SDBTR is 2 MSPS (mega-samples per second). However, the actual sampling rate may be limited by the system clock frequency, the conversion time, and the settling time of the analog input signal.
• Can the ADS7958SDBTR be used in a multi-channel application?
  Yes, the ADS7958SDBTR can be used in a multi-channel application. The device has a serial interface that allows multiple devices to be connected to a single microcontroller or DSP. The devices can be addressed using the Chip Select (CS) pin, allowing multiple devices to be connected and addressed independently.
• What is the power consumption of the ADS7958SDBTR, and how can it be minimized?
  The power consumption of the ADS7958SDBTR depends on the operating mode, sampling rate, and supply voltage. The device has a typical power consumption of 15 mW at 2 MSPS and 3.3 V supply voltage. Power consumption can be minimized by reducing the sampling rate, using the power-down mode, and optimizing the system design to minimize power consumption.
