LTC1445IS datasheet by Linear Technology

LTC1445IS Frequently Asked Questions (FAQs)

• What is the maximum capacitive load that the LTC1445IS can drive?
  The LTC1445IS can drive up to 1000pF of capacitive load, but it's recommended to keep it below 500pF for optimal performance.
• How do I ensure the LTC1445IS is in a stable state during power-up?
  To ensure a stable state during power-up, make sure to connect the VCC pin to a stable voltage source, and add a 0.1uF bypass capacitor between VCC and GND. Also, ensure that the input signals are stable and within the recommended voltage range.
• What is the recommended layout and routing for the LTC1445IS?
  For optimal performance, it's recommended to keep the input and output traces short and away from noise sources. Use a ground plane to reduce noise and ensure that the VCC and GND pins are connected to a low-impedance power supply. Avoid routing high-frequency signals near the device.
• How do I handle ESD protection for the LTC1445IS?
  The LTC1445IS has built-in ESD protection, but it's still recommended to add external ESD protection devices, such as TVS diodes or ESD arrays, to protect the device from electrostatic discharge.
• What is the thermal derating for the LTC1445IS?
  The LTC1445IS has a thermal derating of 6.4mW/°C above 25°C. This means that the device's power dissipation should be reduced as the ambient temperature increases to prevent overheating.
