Description

The LTC2348-18 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, 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 LTC2348-18 analog inputs allow the ADC to directly digitize a variety of signals, simplifying signal chain design. This input signal flexibility, combined with ?3LSB INL, no missing codes at 18 bits, and 96.7dB SNR, makes the LTC2348-18 an ideal choice for many high voltage applications requiring wide dynamic range.The LTC2348-18 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.Applications Programmable Logic Controllers Industrial Process Control Power Line Monitoring Test and Measurement
