DC2365A-F, Demo Board based on LTC2357-16 Buffered Quad, 16-Bit, 350-ksps Simultaneous Sampling SAR ADC

DC2365A-F, Demonstration circuit highlights the LTC2357 family of buffered input ADC. The LTC2357 is a low noise, high speed, 16-bit successive approximation register (SAR) ADC with integrated front end buffers. This ADC accept a wide common mode range. Pico-amp inputs and high CMRR enable these ADCs to connect directly to a wide range of sensors without compromising measurement accuracy. The LTC2357-16 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 2X buffer simplify basic operation while an external reference can be used to increase the input range and the SNR of the ADC
