LTC2357HLX-16#PBF

LTC2357-16 is a buffered quad, 16Bit, 350ksps/Ch differential ±10.24VADC with 30VP-P common mode range. It is a low noise 4-channel simultaneous sampling successive approximation register (SAR) ADC with buffered differential, wide common mode range picoamp inputs. Individual channels may also be disabled to increase throughput on the remaining channels. The integrated picoamp-input analogue buffers, wide input common mode range and 128dB CMRR of the LTC2357-16 allow the ADC to directly digitize a variety of signals using minimal board space and power. It supports pin-selectable SPI CMOS (1.8V to 5V) and LVDS serial interfaces. Between one and four lanes of data output may be employed in CMOS mode, allowing the user to optimize bus width and throughput. Application includes programmable logic controllers, industrial process control, power line monitoring, test and measurement.
