TLC0820AIN datasheet by Texas Instruments

TLC0820AIN Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with TLC0820AIN?
  The maximum clock frequency for TLC0820AIN is 1.5 MHz. However, it's recommended to use a clock frequency of 1 MHz or less to ensure reliable operation.
• How do I handle the output voltage swing of TLC0820AIN?
  The TLC0820AIN has a rail-to-rail output stage, which means the output voltage swing is limited by the supply voltage. To maximize the output voltage swing, use a high-impedance load and ensure the supply voltage is within the recommended range.
• What is the recommended power-on sequence for TLC0820AIN?
  To prevent latch-up and ensure reliable operation, power on the TLC0820AIN in the following sequence: VCC, VREF, and then CLK. Power off in the reverse sequence.
• How do I minimize noise and interference in TLC0820AIN-based designs?
  To minimize noise and interference, use a low-noise power supply, decouple the power pins with capacitors, and use a ground plane to reduce electromagnetic interference. Additionally, use shielding and keep the analog and digital signal paths separate.
• Can I use TLC0820AIN in a multiplexed configuration?
  Yes, TLC0820AIN can be used in a multiplexed configuration. However, ensure that the multiplexer is properly synchronized with the ADC's clock signal, and that the multiplexer's output impedance is low enough to drive the ADC's input capacitance.
