8-channel 18-bit A/D has simultaneous sampling

The LTC2348-18 18-bit, eight-channel simultaneous sampling SAR A/D converter features 200 ks/s per channel read rate. It has ±3 LSB maximum INL, no missing codes, a 96.7dB SNR, and takes only 140 mW when converting all eight channels at full speed.

The IC has an SPI CMOS and LVDS serial output and each input channel can be programed to accept ±10.24 V, 0 to 10.24 V, ±5.12 V, or 0 to 5.12 V. The ICs differential inputs operate over a wide 34 V input common mode range. It has a reference with 20 ppm/°C temperature stability and comes in a lQFP48 package. Priced starting at $23.35 ea/1,000.
