  • [FAQ] ADS1278-SP: Power on / off (up / down) sequencing requirements

    Part Number: ADS1278-SP Other Parts Discussed in Thread: ADS1278 Hello, Are there any power-on or power-off requirements or other specific power-supply recommendations for the ADS1278-SP?

  • [FAQ] ADC128S102-SEP: Can I apply input signals before the analog supply (Va)

    Part Number: ADC128S102-SEP Other Parts Discussed in Thread: ADC128S102 Hello, We have an application where the analog inputs are active before the power up of the analog supply (Va) is complete. What are the implications of this condition and how can…

  • [FAQ] ADC128S102-SEP: Power on / off (up / down) sequencing requirements

    Part Number: ADC128S102-SEP In the datasheet, it is mentioned that analog power rail should ramp before digital power rail during power up. What about during power down? Is there guidance about proper sequencing? Should digital power rail ramp down first…

  • [FAQ] ADS7953: Using GPIO2 and Mode Control Register to select the input range

    Part Number: ADS7953 Hello, I am using the ADS7953 and have a question regarding the use of GPIO2 to control the input range. The input range can be selected via GPIO2 or bit DI06 in the mode control registers. What happens if GPIO2 is used to select…

  • [FAQ] TLA2518: Channel 0 does not work properly as a GPIO

    Part Number: TLA2518 Other Parts Discussed in Thread: ADS7038 , ADS7028 When configuring Channel 0 as a GPIO, the pin does not function as expected. When configured as a GPIO push pull, the pin is always high; and when GPIO0 is configured as an open drain…
