ADI LTC2323IUFD-14#TRPBF

A low noise, high speed dual 14-bit + sign successive approximation register (SAR) ADC with differential inputs and wide input common mode range. Operating from a single 3.3V or 5V supply, it has an 8VP-P differential input range, making it ideal for applications which require a wide dynamic range with high common mode rejection. It achieves ±1LSB INL typical, no missing codes at 14 bits and 80dB SNR.

It has an onboard low drift (20ppm/°C max) 2.048V or 4.096V temperature-compensated reference. It also has a high speed SPI-compatible serial interface that supports CMOS or LVDS. The fast 5Msps per channel throughput with one-cycle latency makes it ideally suited for a wide variety of high speed applications. It dissipates only 38mW per channel and offers nap and sleep modes to reduce the power consumption to 5μW for further power savings during inactive periods.
