AD7989-1BRMZ-RL7 Frequently Asked Questions (FAQs)

  • The recommended layout and routing for the AD7989-1BRMZ-RL7 involves keeping the analog and digital grounds separate, using a solid ground plane, and minimizing the length of the analog input traces. Additionally, it's recommended to place the ADC close to the analog signal source and use a low-pass filter to reduce noise. Refer to the AD7989-1BRMZ-RL7 evaluation board layout as a reference.
  • The AD7989-1BRMZ-RL7 does not require calibration, as it is a self-calibrating ADC. However, it's recommended to perform a system-level calibration to account for any offsets or gains in the signal chain. This can be done by applying a known input voltage and measuring the output code, then adjusting the system gain and offset accordingly.
  • The maximum sampling rate of the AD7989-1BRMZ-RL7 is 1 MSPS. The power consumption of the ADC increases with the sampling rate, but the exact power consumption at maximum sampling rate can be calculated using the formula provided in the datasheet. Typically, the power consumption at 1 MSPS is around 15 mW.
  • The AD7989-1BRMZ-RL7 has internal overvoltage protection on the analog input pins, which can withstand voltages up to ±20 V without damage. However, it's still recommended to use external protection circuitry, such as clamping diodes or resistors, to prevent overvoltage conditions from occurring in the first place.
  • The recommended power supply decoupling scheme for the AD7989-1BRMZ-RL7 involves using a combination of ceramic and electrolytic capacitors to filter out noise and ripple on the power supply lines. A 10 μF ceramic capacitor and a 10 μF electrolytic capacitor in parallel are recommended for the AVDD and DVDD power supply pins.
