ANALOG DEVICES LTC2311CMSE-16#PBF Analogue to Digital Converter, 16 bit, 5 MSPS, Differential, SPI, Single, 3.13 V

LTC2311CMSE-16#PBF is a low noise, high speed 16bit successive approximation register (SAR) ADC with differential inputs and wide input common mode range. Operating from a single 3.3V or 5V supply, the LTC2311-16 has an 8VP-P differential input range, making it ideal for applications that require a wide dynamic range with high common mode rejection. It achieves ±3LSB INL typical, no missing codes at 16 bits, and 81dB SNR typical. It has an onboard low drift (20ppm/°C max) 2.048V or 4.096V temperature-compensated reference and provides an external 1.25V buffered reference input. The LTC2311-16 also has a high-speed SPI-compatible serial interface that supports CMOS or LVDS. The fast 5Msps throughput with one-cycle latency makes the LTC2311-16 ideally suited for a wide variety of high-speed applications. Applications include high-speed data acquisition Systems, communications, remote data acquisition, imaging, optical networking, automotive, and multiphase motor control.
