The LTC2321-12 is a low noise, high speed dual 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 LTC2321-12 has an 8VP-Pdifferential input range, making it ideal for applications which require a wide dynamic range with high common mode rejection. The LTC2321-12 achieves ±0.5LSB INL typical, no missing codes at 12 bits and 73dB SNR.The LTC2321-12 has an onboard low drift (20ppm/°C max) 2.048V or 4.096V temperature-compensated reference. The LTC2321-12 also has a high speed SPI-compatible serial interface that supports CMOS or LVDS. The fast 2Msps per channel throughput with zero cycle latency makes the LTC2321-12 ideally suited for a wide variety of high speed applications. The LTC2321-12 dissipates only 30mW per channel and offers nap and sleep modes to reduce the power consumption to 5μW for further power savings during inactive periods.BitsLTC2321-1212LTC2321-1414LTC2321-1616ApplicationsHigh Speed Data Acquisition SystemsCommunicationsRemote Data AcquisitionImagingOptical NetworkingAutomotiveMultiphase Motor Control
