Texas Instruments ADS8353-Q1 Analog-to-Digital Converters (ADC)

Texas Instruments ADS8353-Q1 16-bit, dual-channel, high-speed, simultaneous-sampling Analog-to-Digital Converter (ADC) supports single-ended and pseudo-differential analog inputs.

The ADS8353-Q1 ADCs include two individually programmable reference sources that can be used for system-level gain calibration. Additionally, the device offers a flexible serial interface that can operate over a wide power supply range, enabling easy communication with various host controllers. Power consumption for a given throughput can be optimized using the two low-power modes supported by the ADS8353-Q1 ADC.

The ADS8353-Q1 is available in a 16-pin TSSOP package and is fully specified over the temperature range of -40°C to +125°C. The Texas Instruments ADS8353-Q1 devices are AEC-Q100 qualified for automotive applications.
