CD4098BMT Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for CD4098BMT?
  The recommended operating voltage range for CD4098BMT is 3V to 18V, although it can operate up to 20V with reduced performance.
• How do I ensure the CD4098BMT is properly biased for linear operation?
  To ensure linear operation, the CD4098BMT requires a bias voltage of at least 2V between the positive supply rail (VCC) and the negative supply rail (VEE). Additionally, the input voltage should be within 2V of the positive supply rail.
• What is the maximum frequency of operation for the CD4098BMT?
  The maximum frequency of operation for the CD4098BMT is approximately 1MHz, although this can vary depending on the specific application and operating conditions.
• How do I handle thermal considerations for the CD4098BMT?
  The CD4098BMT has a maximum junction temperature of 150°C. To ensure reliable operation, it's essential to provide adequate heat sinking and to keep the device within the recommended operating temperature range of -40°C to 85°C.
• Can I use the CD4098BMT in a switching power supply application?
  While the CD4098BMT can be used in switching power supply applications, it's not recommended due to its relatively low switching frequency and high power dissipation. Instead, consider using a dedicated switching regulator IC designed for high-frequency switching applications.
