LTC2324-16 Quad, 16-Bit, 2Msps/Ch Simultaneous Sampling ADC FEATURESDESCRIPTION n 2Msps/Ch Throughput Rate The LTC®2324-16 is a low noise, high speed quad 16-bit n Four Simultaneously Sampling Channels successive approximation register (SAR) ADC with n Guaranteed 16-Bit, No Missing Codes differential inputs and wide input common mode range. n 8VP-P Differential Inputs with Wide Input Operating from a single 3.3V or 5V supply, the LTC2324-16 Common Mode Range has an 8VP-P differential input range, making it ideal for n 82dB SNR (Typ) at fIN = 500kHz applications which require a wide dynamic range with high n –90dB THD (Typ) at fIN = 500kHz common mode rejection. The LTC2324-16 achieves ±2LSB n Guaranteed Operation to 125°C INL typical, no missing codes at 16 bits and 82dB SNR. n Single 3.3V or 5V Supply The LTC2324-16 has an onboard low drift (20ppm/°C max) n Low Drift (20ppm/°C Max) 2.048V or 4.096V 2.048V or 4.096V temperature-compensated reference. Internal Reference The LTC2324-16 also has a high speed SPI-compatible n 1.8V to 2.5V I/O Voltages serial interface that supports CMOS or LVDS. The fast n CMOS or LVDS SPI-Compatible Serial I/O 2Msps per channel throughput with no latency makes the n Power Dissipation 40mW/Ch (Typ) LTC2324-16 ideally suited for a wide variety of high speed n Small 52-Pin (7mm × 8mm) QFN Package applications. The LTC2324-16 dissipates only 40mW per channel and offers nap and sleep modes to reduce the APPLICATIONS power consumption to 26μW for further power savings n High Speed Data Acquisition Systems during inactive periods. n Communications L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks and ThinSOT is a trademark of Analog Devices, Inc.
