AD5520JST Frequently Asked Questions (FAQs)

  • A good layout and routing practice for the AD5520JST involves keeping the analog and digital grounds separate, using a solid ground plane, and minimizing the length of the traces between the device and the analog-to-digital converter (ADC). Additionally, it is recommended to use a low-pass filter or a ferrite bead to filter out high-frequency noise on the power supply lines.
  • The AD5520JST requires a two-point calibration to achieve the highest accuracy. The calibration process involves applying a known input voltage to the device and measuring the output code, and then repeating the process for a second input voltage. The gain and offset errors can then be calculated and used to correct the output codes.
  • The maximum input voltage that the AD5520JST can handle is ±16.5V, which is the absolute maximum rating. However, the recommended input voltage range is ±10V to ensure optimal performance and accuracy.
  • Yes, the AD5520JST can be used in a multiplexed configuration. The device has a built-in multiplexer that allows multiple channels to be connected to a single ADC. The multiplexer can be controlled using the MUXA and MUXB pins, which select the channel to be converted.
  • The power-on reset (POR) timing for the AD5520JST is approximately 10ms. During this time, the device is held in a reset state, and the output codes are undefined. After the POR timing, the device begins to operate normally, and the output codes are valid.
