LTC2333ILX-16#PBF

LTC2333ILX-16#PBF is a 16bit, low noise 8-channel multiplexed 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, this SoftSpan™ ADC can be configured on a conversion-by-conversion basis to accept ±10.24V, 0V to 10.24V, ±5.12V, or 0V to 5.12V signals on any channel. Alternately, the ADC may be programmed to cycle through a sequence of channels and ranges without further user intervention. The integrated picoamp-input analogue buffers, wide input common mode range and 128dB CMRR of the LTC2333- 16 allow the ADC to directly digitize a variety of signals using minimal board space and power. Applications include direct sensor measurement, programmable logic controllers, industrial process control, test and measurement.
