120 140 60 80 100 LT6654 Precision Wide Supply High Output Drive Low Noise Reference Fea T Descrip T n Low Drift: The LT 6654 is a family of small precision voltage ref- A-Grade: 10ppm/C Max erences that offers high accuracy, low noise, low drift, B-Grade: 20ppm/C Max low dropout and low power. The LT6654 operates from n High Accuracy: voltages up to 36V and is fully specified from 55C to A-Grade: 0.05% Max 125C. A buffered output ensures 10mA of output drive B-Grade: 0.10% Max with low output impedance and precise load regulation. n Low Noise: 1.6ppm (0.1Hz to 10Hz) These features, in combination, make the LT6654 ideal P-P n Wide Supply Range to 36V for portable equipment, industrial sensing and control, n Low Thermal Hysteresis: LS8 15ppm (40C to 125C) and automotive applications. n Long Term Drift: (LS8) 15ppm/kHr The LT6654 was designed with advanced manufactur- n Line Regulation (Up to 36V): 5ppm/V Max ing techniques and curvature compensation to provide n Low Dropout Voltage: 100mV Max 10ppm/C temperature drift and 0.05% initial accuracy. n Sinks and Sources 10mA Low thermal hysteresis ensures high accuracy and n Load Regulation at 10mA: 8ppm/mA Max 1.6ppm noise minimizes measurement uncertainty. P-P n Fully Specified from 55C to 125C Since the LT6654 can also sink current, it can operate n Available Output Voltage Options: 1.25V, 2.048V, as a low power negative voltage reference with the same 2.5V, 3V, 3.3V, 4.096V, 5V precision as a positive reference. n Low Profile (1mm) ThinSOT Package and 5mm 5mm Surface Mount Hermetic Package The LT6654 references are offered in 6-lead SOT-23 package and an 8-lead LS8 package. The LS8 is a 5mm a T 5mm surface mount hermetic package that provides n Automotive Control and Monitoring outstanding stability. n High Temperature Industrial L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks and n ThinSOT is a trademark of Linear Technology Corporation.
