TLC7628CDWR datasheet by Texas Instruments

TLC7628CDWR Frequently Asked Questions (FAQs)

• What is the maximum sampling rate of the TLC7628CDWR?
  The maximum sampling rate of the TLC7628CDWR is 200 kHz.
• How do I configure the TLC7628 for differential input mode?
  To configure the TLC7628 for differential input mode, set the DIF bit in the control register (address 0x01) to 1. Additionally, ensure that the input pins are properly connected as differential pairs.
• What is the purpose of the REF pin on the TLC7628CDWR?
  The REF pin is the reference voltage input for the ADC. It sets the full-scale range of the converter. Typically, it is connected to a stable voltage source, such as a voltage regulator or a reference voltage generator.
• Can I use the TLC7628CDWR for a 12-bit or 16-bit ADC application?
  No, the TLC7628CDWR is an 8-bit ADC, and it cannot be used for 12-bit or 16-bit ADC applications. If you need higher resolution, consider other ADCs from Texas Instruments, such as the TLC2543 or TLC2555.
• How do I handle the power-on reset (POR) of the TLC7628CDWR?
  The TLC7628CDWR has a built-in POR circuit that resets the device during power-up. To ensure proper operation, ensure that the power supply voltage (VCC) rises monotonically and reaches the minimum operating voltage (1.8 V) before applying any input signals or starting conversions.
