OPA188AIDGKT datasheet by Texas Instruments

OPA188AIDGKT Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the OPA188AIDGKT?
  The maximum power dissipation of the OPA188AIDGKT 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 OPA188AIDGKT in a feedback loop?
  To ensure stability, it's essential to follow proper PCB layout practices, minimize parasitic capacitance, and use a compensation capacitor (if necessary) as recommended in the datasheet. Additionally, consider using a series resistor (Rs) to isolate the input capacitance and improve stability.
• What is the recommended input and output capacitance for the OPA188AIDGKT?
  The recommended input capacitance is ≤10pF, and the recommended output capacitance is ≤100nF. Exceeding these values may compromise the op-amp's stability and performance.
• Can I use the OPA188AIDGKT as a unity-gain buffer?
  Yes, the OPA188AIDGKT can be used as a unity-gain buffer. However, it's essential to ensure that the input impedance is high enough to avoid loading the input signal, and to consider the op-amp's input bias current and offset voltage.
• How do I handle ESD protection when using the OPA188AIDGKT?
  To handle ESD protection, use a TVS (Transient Voltage Suppressor) diode or a dedicated ESD protection device, such as the TPD1E05U06, in conjunction with the OPA188AIDGKT. This will help protect the op-amp from electrostatic discharge events.
