OPA2348AIDCNR datasheet by Texas Instruments

OPA2348AIDCNR Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the OPA2348AIDCNR?
  The maximum power dissipation of the OPA2348AIDCNR 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 OPA2348AIDCNR in a gain configuration?
  To ensure stability, it's recommended to use a gain resistor (RG) between 1kΩ and 10kΩ, and a feedback capacitor (CF) between 2pF and 10pF. Additionally, the layout should be designed to minimize parasitic capacitance and inductance.
• What is the recommended input common-mode voltage range for the OPA2348AIDCNR?
  The recommended input common-mode voltage range for the OPA2348AIDCNR is between VCC-1.5V and VCC-0.5V, where VCC is the positive supply voltage.
• Can I use the OPA2348AIDCNR in a single-supply configuration?
  Yes, the OPA2348AIDCNR can be used in a single-supply configuration. However, the input common-mode voltage range should be limited to ensure that the input voltage does not exceed the supply voltage.
• How do I reduce noise in my circuit when using the OPA2348AIDCNR?
  To reduce noise, use a low-noise power supply, minimize the length of the input traces, and use a ground plane to reduce electromagnetic interference (EMI). Additionally, consider using a noise filter or a ferrite bead in the power supply lines.
