LTC2320IUKG-16#PBF Datasheet PDF - Linear Technology

●The LTC2320IUKG-16#PBF from Linear Technology is an octal, 16bit, 1.5Msps/Ch simultaneous sampling analogue to digital converter (ADC) in 52 pin QFN package. It is a low noise, high speed octal 16bit SAR ADC with differential inputs and wide input common mode range. Operating from a single 3.3V or 5V supply, the LTC2320-16 has an 8VP-P differential input range, making it ideal for applications which require a wide dynamic range with high common mode rejection. It has an onboard low drift (20ppm/°C max) 2.048V or 4.096V temperature compensated reference. The fast 1.5Msps per channel throughput with no latency makes the LTC2320-16 ideally suited for a wide variety of high speed applications. It dissipates only 20mW per channel and offers nap and sleep modes to reduce power consumption to 26µW for further power savings during inactive periods. It is used in high speed data acquisition systems, communications and optical networking applications.
