Automotive 16-bit 600-kSPS 2-channel simultaneous-sampling SAR ADC with single-ended inputs



The ADS8353-Q1 is a 16-bit, dual-channel, high-speed, simultaneous-sampling, analog-to-digital converter (ADC) that supports single-ended and pseudo-differential analog inputs.

The ADS8353-Q1 includes two individually programmable reference sources that can be used for system-level gain calibration. Also, a flexible serial interface that can operate over a wide power-supply range enables easy communication with a large variety of host controllers. Power consumption for a given throughput can be optimized by using the two low-power modes supported by the device. The ADS8353-Q1 is fully specified over the temperature range (–40°C to +125°C) and is available in a 16-pin TSSOP package.
