AD790JR Frequently Asked Questions (FAQs)

  • The AD790JR is a high-precision, low-noise amplifier, and proper layout and placement are crucial. It is recommended to place the AD790JR close to the signal source, use a ground plane, and keep the input traces as short as possible. Additionally, decoupling capacitors should be placed close to the device to minimize noise.
  • The AD790JR is specified to operate from -40°C to +125°C. Ensure that the device is properly heat-sinked, and the ambient temperature is within the specified range. Also, consider the power dissipation and thermal resistance of the device when designing the system.
  • The recommended input impedance for the AD790JR is 1 kΩ or higher. A lower input impedance can lead to reduced gain accuracy and increased noise. It is essential to ensure that the input impedance is within the recommended range to achieve optimal performance.
  • To minimize EMI and RFI, use proper shielding, grounding, and filtering techniques. Ensure that the AD790JR is placed in a shielded environment, and use filters or chokes to reduce high-frequency noise. Additionally, consider using a Faraday cage or a shielded enclosure to reduce electromagnetic radiation.
  • The recommended power supply decoupling for the AD790JR is to use a 10 μF capacitor in parallel with a 100 nF capacitor, placed close to the device. Proper decoupling ensures that the amplifier operates with minimal noise and ripple, resulting in optimal performance.
