LTC2325HUKG-14#PBF

LTC2325HUKG-14#PBF is a low noise, high-speed quad 14bit + 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 LTC2325-14 has an 8VP-P differential input range, making it ideal for applications that require a wide dynamic range with high common mode rejection. The LTC2325-14 achieves ±1LSB INL typical, no missing codes at 14 bits and 81dB SNR. The LTC2325-14 has an onboard low drift (20ppm/°C max) 2.048V or 4.096V temperature-compensated reference. The LTC2325-14 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 LTC2325-14 ideally suited for a wide variety of high speed applications. Applications include high speed data acquisition Systems, communications, optical networking, and multiphase motor control.
