Linear Technology LTC2341HUH-18#TRPBF

Description
The LTC2341-18 is a dual, 18-bit, 666ksps/ch differential SoftSpan ADC with wide input common mode range. It features guaranteed 18-bit, no missing codes, and differential, wide common mode range inputs. The per-channel SoftSpan input ranges include: ±4.096V, 0V to 4.096V, ±2.048V, 0V to 2.048V, 5V, 0V to 5V, ±2.5V, and 0V to 2.5V. It offers 95dB single-conversion SNR (typical), -114dB THD (typical) at fiN = 2kHz, and 105dB CMRR (typical) at fIN = 200Hz. The LTC2341-18 has rail-to-rail input overdrive tolerance, guaranteed operation to 125°C, and an integrated reference and buffer (4.096V). It supports SPI CMOS (1.8V to 5V) and LVDS serial I/O, has an internal conversion clock with no cycle latency, and dissipates 74mW of power (typical). The LTC2341-18 comes in a 32-lead (5mm x 5mm) QFN package.
