The AD10680 is a 16-bit analog-to-digital converter (ADC)
with a transformer-coupled, analog input and digital
postprocessing for enhanced signal-to-noise ratio (SNR). The
product operates at a 100 MSPS conversion rate with
outstanding dynamic performance. Internal filters can be
digitally selected for the appropriate bandwidth or externally
The AD10680 requires 5.0 V analog, 3.3 V analog, 3.3 V digital,
2.5 V digital, and a 1.2V digital supply, and a differential encode
signal. No external reference is required.
Performance is rated over a 0°C to 60°C case temperature range.
