Analog Devices LTC2311-12 Product Info

The LTC2311-12 is a low noise, high speed 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 LTC2311-12 has an 8V_P-P differential input range, making it ideal for applications which require a wide dynamic range with high common mode rejection. The LTC2311-12 achieves ±0.25LSB INL typical, no missing codes at 12 bits and 73dB SNR typical.

The LTC2311-12 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 LTC2311-12 also has a high speed SPI-compatible serial interface that supports CMOS or LVDS. The fast 5Msps throughput with one-cycle latency makes the LTC2311-12 ideally suited for a wide variety of high speed applications. The LTC2311-12 dissipates only 50mW with a 5V supply and offers nap and sleep modes to reduce the power consumption for further power savings during inactive periods.
