ADS8668IDBTR – TEXAS INSTRUMENTS

The Texas Instruments ADS8668IDBTR is a 16-bit, low-power, successive approximation register (SAR) analog-to-digital converter (ADC) housed in a 20-pin TSSOP package. Operating from a 2.7V to 5.5V supply voltage, it boasts a maximum sampling rate of 1 MSPS and achieves a typical total unadjusted error of ±1 LSB. The device features an internal reference, eliminating the need for external voltage references, simplifying design and reducing component count. It incorporates a power-down mode to minimize power consumption, crucial for battery-powered applications. The ADS8668IDBTR offers a single-ended input, making it suitable for straightforward signal acquisition. Common use cases include industrial process control, portable instrumentation, and data acquisition systems requiring high resolution and moderate sampling speeds. Its low power consumption and integrated reference make it advantageous in space-constrained and battery-operated designs where minimizing external components is paramount. The device’s inherent accuracy minimizes the need for extensive calibration routines, further enhancing its suitability for cost-sensitive applications. Note its relatively low sampling rate compared to higher-speed ADCs; consider alternatives if higher bandwidth is required.
