Description

The LTC2341-18 is an 18-bit, low noise 2-channel simultaneous sampling successive approximation register (SAR) ADC with differential, wide common mode range inputs. Operating from a 5V supply and using the internal reference and buffer, both channels of this SoftSpan? ADC can be independently configured on a conversion-by-conversion basis to accept ?4.096V, 0V to 4.096V, ?2.048V, or 0V to 2.048V signals. One channel may also be disabled to increase throughput on the other channel.The wide input common mode range and 105dB CMRR of the LTC2341-18 analog inputs allow the ADC to directly digitize a variety of signals, simplifying signal chain design. This input signal flexibility, combined with ?4LSB INL, no missing codes at 18 bits, and 95dB SNR, makes the LTC2341-18 an ideal choice for many applications requiring wide dynamic range.The LTC2341-18 supports pin-selectable SPI CMOS (1.8V to 5V) and LVDS serial interfaces. Either one or two 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 Medical Imaging High Speed Data Acquisition
