Description
AI
The LTC2325-12 is a low noise, high speed quad 12-bit + 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 LTC2325-12 has an 8VP-Pdifferential input range, making it ideal for applications which require a wide dynamic range with high common mode rejection. The LTC2325-12 achieves ±0.5LSB INL typical, no missing codes at 12 bits and 77dB SNR.The LTC2325-12 has an onboard low drift (20ppm/°C max) 2.048V or 4.096V temperature-compensated reference. 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.ApplicationsHigh Speed Data Acquisition SystemsCommunicationsOptical NetworkingMultiphase Motor Control
