Introduction

AI Translation

The LTC2358 - 18 is an 18 - bit, low noise 8 - channel simultaneous sampling successive approximation register (SAR) ADC with buffered differential, wide common mode range picoamp inputs. Operating from a 5V low voltage supply, flexible high voltage supplies, and using the internal reference and buffer, each channel of this SoftSpan ADC can be independently configured on a conversion - by - conversion basis to accept ±10.24V, 0V to 10.24V, ±5.12V, or 0V to 5.12V signals. Individual channels may also be disabled to increase throughput on the remaining channels. The integrated picoamp - input analog buffers, wide input common mode range and 128dB CMRR of the LTC2358 - 18 allow the ADC to directly digitize a variety of signals using minimal board space and power. This input signal flexibility, combined with ±3.5LSB INL, no missing codes at 18 bits, and 96.4dB SNR, makes the LTC2358 - 18 an ideal choice for many high voltage applications requiring wide dynamic range. The LTC2358 - 18 supports pin - selectable SPI CMOS (1.8V to 5V) and LVDS serial interfaces. Between one and eight lanes of data output may be employed in CMOS mode, allowing the user to optimize bus width and throughput.
