DC2520A-B, Demo Board Based on LTC2344-16 Quad, 16-Bit, 400ksps Differential ±5V Input SoftSpan ADC with Wide Input Common Mode Range

DC2520A-B, Demonstration Circuit shows the proper way to drive the LTC2344-16 ADC. The LTC2344-16 is a low noise, high speed, simultaneous sampling 16-bit successive approximation register (SAR) ADC. The LTC2344 has a flexible SoftSpan interface that allows conversion-by-conversion control of the input voltage span on a per-channel basis. An internal 2.048V reference and 2+ buffer simplify basic operation while an external reference can be used to increase the input range and the SNR of the ADC
