LTC2311-14 - 14-Bit + Sign, 5Msps Differential Input ADC with Wide Input Common Mode Range
The LTC®2311-14 is a low noise, high speed 14-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 LTC2311- 14 has an 8VP-P differential input range, making it ideal for applications which require a wide dynamic range with high common mode rejection. The LTC2311-14 achieves ±0.75LSB INL typical, no missing codes at 14 bits and 80dB SNR typical.
The LTC2311-14 has an onboard low drift (20ppm/°C max) 2.048V or 4.096V temperature compensated reference and provides an external 1.25V buffered reference input. The LTC2311-14 also has a high speed SPI-compatible serial interface that supports CMOS or LVDS. The fast 5Msps throughput with one-cycle latency makes the LTC2311-14 ideally suited for a wide variety of high speed applications. The LTC2311-14 dissipates only 50mW with a 5V supply and offers nap and sleep modes to reduce the power consumption to 5μW for further power savings during inactive periods.
