LTC2323HUFD-16#PBF

LTC2323HUFD-16#PBF is a low noise, high-speed dual 16bit successive approximation register (SAR) ADC with differential inputs and a wide input common mode range. Operating from a single 3.3V or 5V supply, the LTC2323-16 has an 8VP-P differential input range, making it ideal for applications that require a wide dynamic range with high common mode rejection. The LTC2323-16 achieves ±4LSB INL typical, no missing codes at 16 bits and 81dB SNR. The LTC2323-16 has an onboard low drift (20ppm/°C max) 2.048V or 4.096V temperature-compensated reference. The LTC2323-16 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 the LTC2323-16 ideally suited for a wide variety of high-speed applications. It is used in applications such as high speed data acquisition systems, communications, remote data acquisition, imaging, optical networking, automotive, multiphase motor control.
