TLC2652CN datasheet by Texas Instruments

TLC2652CN Frequently Asked Questions (FAQs)

• What is the recommended power-on sequence for the TLC2652CN?
  The recommended power-on sequence is to apply VCC first, followed by VREF, and then the analog input signal. This ensures proper operation and prevents latch-up.
• How do I handle the output current of the TLC2652CN?
  The TLC2652CN can source or sink up to 20mA of output current. To handle this, use a buffer or a voltage follower if the output current exceeds the maximum rating of the next stage in the circuit.
• What is the effect of temperature on the TLC2652CN's performance?
  The TLC2652CN's performance is affected by temperature, with a typical temperature coefficient of -0.05%/°C for the gain and -0.1%/°C for the offset voltage. Ensure proper thermal management and consider temperature compensation if necessary.
• Can I use the TLC2652CN in a single-supply configuration?
  Yes, the TLC2652CN can be used in a single-supply configuration, but the input common-mode range is limited to VCC - 1.5V. Ensure that the input signal is within this range to maintain proper operation.
• How do I layout the PCB to minimize noise and interference with the TLC2652CN?
  Use a multi-layer PCB with a solid ground plane, keep the analog and digital grounds separate, and use shielding and filtering to minimize noise and interference. Also, keep the input and output traces short and away from each other.
