The LTC2382-16 is a low noise, low power, high speed 16-bit successive approximation register (SAR) ADC. Operating from a 2.5V supply, the LTC2382-16 has a ±2.5V fully differential input range. The LTC2382-16 consumes only 6.5mW and achieves ±2LSB INL max, no missing codes at 16-bits and 92dB SNR.
The LTC2382-16 has a high speed SPI-compatible serial interface that supports 1.8V, 2.5V, 3.3V and 5V logic while also featuring a daisychain mode. The fast 500ksps throughput with no cycle latency makes the LTC2382-16 ideally suited for a wide variety of high speed applications. An internal oscillator sets the conversion time, easing external timing considerations. The LTC2382-16 automatically powers down between conversions, leading to reduced power dissipation that scales with the sampling rate.
The LTC2382-16 features a proprietary sampling architecture that enables the ADC to begin acquiring the next sample during the current conversion. The resulting extended acquisition time of 1.25μs allows the use of extremely low power ADC drivers.

Software & Systems Requirements
Tools & Simulations
Linduino is Analog Devices’ Arduino compatible system for developing and distributing firmware libraries and example code for our integrated circuits. Each Linduino-supported product includes an example main program, defined in the LTSketchbook/Part Number folder and driver code, defined in the LTSketchbook/libraries folder.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
