LTC2348CLX-16#PBF

LTC2348CLX-16#PBF is a 16bit, low noise 8-channel simultaneous sampling successive approximation register (SAR) ADC with differential, wide common mode range 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 wide input common mode range and 118dB CMRR of the LTC2348-16 analogue inputs allow the ADC to directly digitize a variety of signals, simplifying signal chain design. Applications include programmable logic controllers, industrial process control, power line monitoring, test and measurement.
