ADS7950SDBT Frequently Asked Questions (FAQ)
-
Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital traces separate. Additionally, use a low-ESR capacitor for the AVDD pin and a 0.1uF capacitor for the DVDD pin. Route the analog input traces away from the digital traces and keep them as short as possible.
-
To optimize the ADS7950SDBT for low-power operation, use the lowest possible clock frequency, disable the internal reference voltage, and use the power-down mode when not converting. Additionally, consider using a lower supply voltage and reducing the analog input range.
-
The ADS7950SDBT has an internal calibration circuit that can be used to calibrate the device. Apply a known input voltage to the analog input pins, and then use the CAL pin to initiate the calibration process. The device will then adjust its internal offset and gain to match the input voltage.
-
The ADS7950SDBT outputs 16-bit data in a binary two's complement format. The data is output on the D[15:0] pins, with D[15] being the MSB and D[0] being the LSB. The data is valid on the rising edge of the SCLK pin.
-
The ADS7950SDBT has a maximum conversion rate of 250,000 samples per second (SPS) at a clock frequency of 10 MHz. However, the actual conversion rate may be limited by the analog input bandwidth and the system's overall noise performance.
