AD7891APZ-2 Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC before applying VREF. This ensures that the internal reference voltage is stable before the ADC starts converting.
  • To minimize noise and ensure accurate conversions, keep the analog and digital grounds separate, use a solid ground plane, and keep the analog input traces away from digital traces. Also, use a low-ESR capacitor for the VREF pin and a 0.1uF capacitor for the VCC pin.
  • The maximum sampling rate of the AD7891APZ-2 is 250 kSPS. As the sampling rate increases, the power consumption also increases. At maximum sampling rate, the power consumption is approximately 15 mW.
  • The AD7891APZ-2 outputs 12-bit data in a serial format. The output data is in two's complement format, with the most significant bit (MSB) first. The output data can be handled using a microcontroller or a dedicated interface IC.
  • The AD7891APZ-2 operates over a temperature range of -40°C to +85°C. Temperature affects the ADC's offset and gain errors, which can be calibrated out using external circuitry or software correction.
