LTC2357CLX-16#PBF

LTC®2357-16 is a 16bit, 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. It supports pin-selectable SPI CMOS 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.
