TLC2202AMJG datasheet by Texas Instruments

TLC2202AMJG Frequently Asked Questions (FAQs)

• What is the recommended layout and routing for the TLC2202AMJG to minimize noise and ensure optimal performance?
  Texas Instruments recommends a star-ground configuration, with the analog and digital grounds separated and connected at a single point. Additionally, keep the input and output traces short and away from digital signals, and use a solid ground plane to reduce noise.
• How do I handle the power-on reset (POR) and brown-out reset (BOR) in my design?
  The TLC2202AMJG has a built-in POR and BOR circuitry. To handle these, ensure that the power supply ramps up slowly (typically 10ms to 100ms) and that the voltage stays above the minimum operating voltage (VDD) during operation. You can also add external circuitry to detect and respond to POR and BOR events.
• What is the maximum capacitive load that the TLC2202AMJG can drive?
  The TLC2202AMJG can drive capacitive loads up to 100pF. However, it's recommended to keep the capacitive load below 50pF to ensure stability and optimal performance. Exceeding this limit may result in oscillations or reduced output swing.
• How do I ensure electromagnetic compatibility (EMC) and reduce electromagnetic interference (EMI) in my design?
  To ensure EMC and reduce EMI, use a shielded enclosure, keep the TLC2202AMJG away from high-frequency sources, and use a common-mode choke or ferrite bead on the power supply lines. Additionally, use a low-pass filter on the output and input signals, and consider using a spread-spectrum clock generator.
• What is the recommended operating temperature range for the TLC2202AMJG?
  The TLC2202AMJG is specified to operate from -40°C to 125°C. However, it's recommended to operate the device within the industrial temperature range (-40°C to 85°C) for optimal performance and reliability.
