LTC2323-12 - Dual, 12-Bit + Sign, 5Msps Differential Input ADC with Wide Input Common Mode Range
The LTC®2323-12 is a low noise, high speed dual 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 LTC2323-12 has an 8VP-P differential input range, making it ideal for applications which require a wide dynamic range with high common mode rejection. The LTC2323-12 achieves ±0.5LSB INL typical, no missing codes at 12 bits and 73dB SNR.
The LTC2323-12 has an onboard low drift (20ppm/°C max) 2.048V or 4.096V temperature-compensated reference. The LTC2323-12 also has a high speed SPI-compatible serial interface that supports CMOS or LVDS. The fast 5Msps per channel throughput with one-cycle latency makes the LTC2323-12 ideally suited for a wide variety of high speed applications. The LTC2323-12 dissipates only 38mW per channel and offers nap and sleep modes to reduce the power consumption to 5μW for further power savings during inactive periods.
