Linear Technology LTC2323HUFD-14#TRPBF

Description
The LTC2323-14 is a low noise, high speed dual 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 LTC2323-14 has an 8Vp.p differential input range, making it ideal for applications which require a wide dynamic range with high common mode rejection. The LTC2323-14 achieves 1LSB INL typical, no missing codes at 14 bits and 80dB SNR. The LTC2323-14 has an onboard low drift (20ppm/°C max) 2.048V or 4.096V temperature-compensated reference. The LTC2323-14 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 LTC2323-14 ideally suited for a wide variety of high speed applications. The LTC2323-14 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.
