ANALOG DEVICES LTC2323CUFD-12#PBF Analogue to Digital Converter, 12 bit, 5 MSPS, Differential, Pseudo Differential, Single Ended

LTC2323CUFD-12#PBF is a low noise, high-speed dual 12bit + sign successive approximation register (SAR) ADC with differential inputs and wide input common mode range. Operating from a single 3.3V or 5V supply, the LTC2323-12 has an 8VP-P differential input range, making it ideal for applications that require a wide dynamic range with high common mode rejection. The LTC2323-12 has a high speed SPI-compatible serial interface that supports CMOS or LVDS. The fast 5Msps per channel throughput with one-cycle latency makes the device ideally suited for a wide variety of high speed applications. The LTC2323-12 dissipates only 38mW per channel and offers nap and sleep modes to reduce the power consumption to 5 ?W for further power savings during inactive periods. Applications include high speed data acquisition systems, communications, remote data acquisition, imaging, optical networking, and multiphase motor control.
