LT LTC2345HUK-16#PBF

Overview

The LTC�2345-18 is an 18-bit, 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 and using the internal reference and buffer, each channel of this SoftSpanTM ADC can be independently configured on a conversion-by-conversion basis to accept �4.096, 0V to 4.096V, �2.048V, or 0V to 2.048V signals. Individual channels may also be disabled to increase throughput on the remaining channels. The wide input common mode range and 102dB CMRR of the LTC2345-18 analog inputs allow the ADC to directly digitize a variety of signals, simplifying signal chain design. This input signal flexibility, combined with �5LSB INL, no missing codes at 18 bits, and 91.8dB SNR, makes the LTC2345-18 an ideal choice for many applications requiring wide dynamic range. The LTC2345-18 supports pin-selectable SPI CMOS (1.8V to 5V) and LVDS serial interfaces. Between one and eight lanes of data output may be employed in CMOS mode, allowing the user to optimize bus width and throughput
