DC2326A-A, Demo Board Using LTC2345-18 Octal, 18-Bit, 200ksps Simultaneous Sampling SAR ADC

DC2326A-A, Demo Board Using LTC2345-18 Octal, 18-Bit, 200ksps Simultaneous Sampling SAR ADC. The Demonstration Circuit shows the proper way to drive the LTC2345 ADC. The LTC2345 is a low noise, high speed, simultaneous sampling 18-bit successive approximation register (SAR) ADC. The LTC2345 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
