Description
The ADS850 is a high dynamic range, 14-bit Analog-to-Digital Converter (ADC) that utilizes a fully differential input, allowing for either single-ended or differential input interface over varying input spans. This converter features digital error correction techniques ensuring 14-bit linearity and a calibration procedure that corrects for capacitor and gain mismatches. The ADS850 also includes a high-bandwidth track-and-hold that provides excellent spurious performance up to and beyond the Nyquist rate.
The ADS850 provides an internal reference that can be programmed for a 2Vp-p input range for the best spurious performance and ease of driving. Alternatively, the 4Vp-p input range can be used for the lowest input referred noise, offering superior signal-to-noise performance for imaging applications. There is also the capability to set the range between 2Vp-p and 4Vp-p, or to use an external reference. The ADS850 also provides an over-range indicator flag to indicate if the input has exceeded the full-scale input range of the converter.
The low distortion and high signal-to-noise performance provide the extra margin needed for communications, imaging, and test instrumentation applications. The ADS850 is available in a TQFP-48 package.
