16-Bit, 2Msps Differential Input ADC with Wide Input Common Mode Range

The LTC2310-16 is a low noise, high speed 16-bit successive approximation register (SAR) ADC with differential inputs and wide input common mode range. Operating from a single 3.3V or 5V supply, the LTC2310-16 has an 8VP-P differential input range, making it ideal for applications which require a wide dynamic range with high common mode rejection. The LTC2310-16 achieves ±3LSB INL typical, no missing codes at 16 bits and 82dB SNR typical.

The LTC2310-16 has an on-board low drift (20ppm/°C max) 2.048V or 4.096V temperature-compensated reference and provides an external 1.25V buffered reference input. The LTC2310-16 also has a high speed SPI-compatible serial interface that supports CMOS or LVDS. The fast 2Msps throughput with no cycle latency makes the LTC2310-16 ideally suited for a wide variety of high speed applications. The LTC2310-16 dissipates only 35mW with a 5V supply and offers nap and sleep modes to reduce the power consumption for further power savings during inactive periods.
