LM13700M Frequently Asked Questions (FAQs)

• What is the maximum power supply voltage that can be used with the LM13700M?
  The maximum power supply voltage for the LM13700M is 30V. Exceeding this voltage can cause damage to the device.
• How do I ensure stability in the voltage-controlled oscillator (VCO) circuit?
  To ensure stability in the VCO circuit, it's essential to use a high-quality capacitor for the timing capacitor (CT) and to keep the resistance of the timing resistor (RT) as low as possible. Additionally, the power supply voltage should be well-regulated and decoupled.
• What is the recommended operating temperature range for the LM13700M?
  The recommended operating temperature range for the LM13700M is -25°C to 85°C. Operating the device outside this range can affect its performance and reliability.
• How do I reduce noise and interference in the LM13700M circuit?
  To reduce noise and interference, use a well-regulated power supply, decouple the power supply lines with capacitors, and keep the circuit layout as compact as possible. Additionally, use shielding and grounding techniques to minimize electromagnetic interference (EMI).
• What is the maximum frequency range of the VCO in the LM13700M?
  The maximum frequency range of the VCO in the LM13700M is approximately 1MHz to 10MHz, depending on the values of the timing capacitor (CT) and resistor (RT).
