LTC2325IUKG-12#PBF

LTC®2325-12 is a low noise, high speed quad 12bit + sign successive approximation register (SAR) ADC with differential inputs and wide input common mode range. This the LTC2325-12 has an 8VP-P differential input range, making it ideal for applications which require a wide dynamic range with high common mode rejection. The LTC2325-12 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 LTC2325-12 ideally suited for a wide variety of high speed applications. The LTC2325-12 dissipates only 45mW per channel and offers nap and sleep modes to reduce the power consumption to 26μW for further power savings during inactive periods. Application includes high speed data acquisition systems, communications, optical networking, multiphase motor control.
