Demonstration circuit 2412A shows the proper way to drive the LTC2335 ADC. The LTC2335 is a low noise, high speed, 8-channel 16-/18-bit successive approximation register (SAR) ADC. The LTC2335 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.
