DC2365A-A

Demonstration circuit 2365A highlights the LTC2358 family of buffered input ADCs. The LTC2358-18 low noise, high speed, 18bit successive approximation register (SAR) ADCs with integrated front end buffers. This ADC accepts 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 LTC2358-18 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.
