OPA692IDBVT datasheet by Texas Instruments

OPA692IDBVT Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the OPA692IDBVT?
  The maximum power dissipation of the OPA692IDBVT 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 OPA692IDBVT in a high-gain configuration?
  To ensure stability, it's recommended to use a compensation capacitor (CC) between the output and the inverting input pins. The value of CC depends on the gain and bandwidth requirements of the application. A good starting point is a 10pF to 22pF capacitor.
• What is the recommended layout and routing for the OPA692IDBVT to minimize noise and EMI?
  To minimize noise and EMI, it's recommended to use a star-ground configuration, keep the input and output traces short and away from each other, and use a ground plane to shield the device. Additionally, decoupling capacitors should be placed close to the device's power pins.
• Can I use the OPA692IDBVT in a single-supply configuration?
  Yes, the OPA692IDBVT can be used in a single-supply configuration. However, the input common-mode voltage range is limited to VCC-1.5V to VCC+0.5V. To ensure proper operation, the input signal should be biased within this range.
• What is the recommended input impedance for the OPA692IDBVT?
  The recommended input impedance for the OPA692IDBVT is 1kΩ or higher. This ensures that the input stage of the op-amp is not overloaded, and the device operates within its specified parameters.
