LTC2311-12 12-Bit + Sign, 5Msps Differential Input ADC with Wide Input Common Mode Range Fea T Descrip T n 5Msps Throughput Rate The LTC 2311-12 is a low noise, high speed 12-bit + n 0.25LSB INL (Typ), 1LSB INL Guaranteed sign successive approximation register (SAR) ADC with n Guaranteed 12-Bit, No Missing Codes differential inputs and wide input common mode range. n 8V Differential Inputs with Wide Input Common Operating from a single 3.3V or 5V supply, the LTC2311- P-P Mode Range 12 has an 8V differential input range, making it ideal P-P n 73dB SNR (Typ) at f = 2.2MHz for applications which require a wide dynamic range with IN n 85dB THD (Typ) at f = 2.2MHz high common mode rejection. The LTC2311-12 achieves IN n Guaranteed Operation 40C to 125C 0.25LSB INL typical, no missing codes at 12 bits and n Single 3.3V or 5V Supply 73dB SNR typical. n Low Drift (20ppm/C Max) 2.048V or 4.096V Internal The LTC2311-12 has an onboard low drift (20ppm/C max) Reference with 1.25V External Reference Input 2.048V or 4.096V temperature compensated reference n 1.8V to 2.5V I/O Voltages and provides an external 1.25V buffered reference input. n CMOS or LVDS SPI-Compatible Serial I/O The LTC2311-12 also has a high speed SPI-compatible n Power Dissipation 50mW at V = 5V (Typ) DD serial interface that supports CMOS or LVDS. The fast n Small 16-Lead (4mm 5mm) MSOP Package 5Msps throughput with one-cycle latency makes the LTC2311-12 ideally suited for a wide variety of high speed a T applications. The LTC2311-12 dissipates only 50mW with n a 5V supply and offers nap and sleep modes to reduce High Speed Data Acquisition Systems n the power consumption for further power savings during Communications n inactive periods.
