OPA2313IDGKR datasheet by Texas Instruments

OPA2313IDGKR Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the OPA2313IDGKR?
  The maximum power dissipation of the OPA2313IDGKR is 670mW, which is calculated based on the maximum junction temperature (TJ) of 150°C and the thermal resistance (θJA) of 125°C/W.
• How do I ensure stability when using the OPA2313IDGKR in a gain configuration?
  To ensure stability, it's recommended to use a gain resistor (RG) between 1kΩ to 10kΩ, and a feedback capacitor (CF) between 2pF to 10pF. Additionally, the layout should be designed to minimize parasitic capacitance and inductance.
• What is the recommended input and output capacitance for the OPA2313IDGKR?
  The recommended input capacitance is 10pF to 100pF, and the recommended output capacitance is 10nF to 100nF. However, the optimal capacitance values may vary depending on the specific application and layout.
• Can I use the OPA2313IDGKR in a high-temperature environment?
  The OPA2313IDGKR is specified to operate from -40°C to 125°C. However, the device's performance may degrade at high temperatures, and the maximum junction temperature (TJ) should not exceed 150°C.
• How do I reduce noise and electromagnetic interference (EMI) in my OPA2313IDGKR circuit?
  To reduce noise and EMI, use a low-pass filter at the input, keep the signal traces short and away from noise sources, use a ground plane, and consider adding shielding or a Faraday cage around the circuit.
