LTC2333HLX-16#PBF

LTC2333HLX-16#PBF is a 16bit, low noise 8-channel multiplexed successive approximation register (SAR) ADC with buffered differential, wide common mode range picoamp inputs. 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 device allow the ADC to directly digitize a variety of signals using minimal board space and power. This input signal flexibility, combined with ±1LSB INL, no missing codes at 16 bits, and 94.2dB SNR, makes the device an ideal choice for many high-voltage applications requiring wide dynamic range. It supports pin-selectable SPI CMOS (1.8V to 5V) and LVDS serial interfaces. Applications include direct sensor measurement, programmable logic controllers, industrial process control, test and measurement.
