TLC4502IDR datasheet by Texas Instruments

TLC4502IDR Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for TLC4502IDR?
  The recommended operating voltage range for TLC4502IDR is 4.5V to 16V.
• How do I ensure the TLC4502IDR is properly biased for optimal performance?
  To ensure proper biasing, connect the midpoint of the voltage divider (pin 3) to a quiet analog ground, and decouple the power supply pins (VCC and GND) with a 0.1uF capacitor.
• What is the maximum output current of the TLC4502IDR?
  The maximum output current of the TLC4502IDR is 20mA per channel.
• How do I protect the TLC4502IDR from overvoltage conditions?
  Use a voltage clamp or a transient voltage suppressor (TVS) diode to protect the TLC4502IDR from overvoltage conditions.
• What is the recommended layout and routing for the TLC4502IDR?
  Keep the analog and digital grounds separate, use a star-ground configuration, and keep the signal traces short and direct to minimize noise and interference.
