ADI LTC2324IUKG-12#TRPBF

A low noise, high speed quad 12-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 ±0.5LSB INL typical, no missing codes at 12 bits and 78dB 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 2Msps per channel throughput with no latency makes it ideally suited for a wide variety of high speed applications. It dissipates only 40mW per channel and offers nap and sleep modes to reduce the power consumption to 26μW for further power savings during inactive periods.
