FAQs

What is ADS8688IDBT?

The ADS8688IDBT is a high-performance, 16-bit analog-to-digital converter (ADC) designed by Texas Instruments. It is designed for applications requiring high-resolution, high-speed conversions, such as industrial automation, test and measurement equipment, and data acquisition systems.

How Does ADS8688IDBT Work?

The ADS8688IDBT operates by converting analog input signals into digital data with high precision and speed. It utilizes a successive approximation register (SAR) architecture to achieve high-resolution conversions at fast sampling rates. The ADC features low-power operation and a flexible interface, making it suitable for a wide range of precision measurement applications.

How Many Pins does ADS8688IDBT have and What are the Functions of the Pinout Configuration?

The ADS8688IDBT is housed in a 16-pin TSSOP (Thin Shrink Small Outline Package) package. The pinout configuration includes:

  • AVDD, DVDD: Analog and digital power supply pins, respectively.
  • AGND, DGND: Analog and digital ground pins, respectively.
  • VIN(0-7): Analog input voltage pins for differential or single-ended measurements.
  • REFP, REFN: Reference voltage input pins.
  • EXTCLK, CS, SCLK, DOUT/SDI, DIN/SDO: Serial interface control and data pins.
  • EOS/SYNC: End of conversion/synchronization output pin.
