LTC2310-16 16-Bit, 2Msps Differential Input ADC with Wide Input Common Mode Range Fea T Descrip T n 2Msps Throughput Rate The LTC 2310-16 is a low noise, high speed 16-bit n 3LSB INL (Typ), 8LSB INL Guaranteed successive approximation register (SAR) ADC with n Guaranteed 16-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 LTC2310-16 P-P Mode Range has an 8V differential input range, making it ideal for P-P n 82dB SNR (Typ) at f = 500kHz applications which require a wide dynamic range with IN n 93dB THD (Typ) at f = 500kHz high common mode rejection. The LTC2310-16 achieves IN n No Cycle Latency 3LSB INL typical, no missing codes at 16 bits and 82dB n Guaranteed Operation 40C to 125C SNR typical. n Single 3.3V or 5V Supply The LTC2310-16 has an onboard low drift (20ppm/C max) n Low Drift (20ppm/C Max) 2.048V or 4.096V Internal 2.048V or 4.096V temperature-compensated reference and Reference with 1.25V External Reference Input provides an external 1.25V buffered reference input. The n 1.8V to 2.5V I/O Voltages LTC2310-16 also has a high speed SPI-compatible serial n CMOS or LVDS SPI-Compatible Serial I/O interface that supports CMOS or LVDS. The fast 2Msps n Power Dissipation 35mW at V = 5V (Typ) DD throughput with no cycle latency makes the LTC2310-16 n Small 16-Lead (4mm 5mm) MSOP Package ideally suited for a wide variety of high speed applications. The LTC2310-16 dissipates only 35mW with a 5V supply a T and offers nap and sleep modes to reduce the power n consumption for further power savings during inactive High Speed Data Acquisition Systems n periods.
