LTC6652 Precision Low Drift Low Noise Buffered Reference Features Description n Low Drift: The LTC 6652 family of precision, low drift, low noise A-Grade 5ppm/C Max references is fully specified over the temperature range B-Grade 10ppm/C Max (MSOP8) of 40C to 125C. High order curvature compensation B-Grade 8ppm/C Max (LS8) allows these references to achieve a low drift of less than n High Accuracy: 5ppm/C with a predictable temperature characteristic and A-Grade 0.05% Max an output voltage accuracy of 0.05%. The performance B-Grade 0.1% Max over temperature should appeal to automotive, high perfor- n Low Noise: 2.1ppm (0.1Hz to 10Hz) mance industrial and other high temperature applications. P-P n 100% Tested at 40C, 25C and 125C The LTC6652 voltage references can be powered from n Sinks and Sources Current: 5mA supply voltages up to 13.2V. They boast low noise, ex- n Low Power Shutdown: <2A Maximum cellent load regulation, source and sink capability and n Thermal Hysteresis (LS8): 45ppm (40C to 125C) exceptional line rejection, making them a superior choice n Long-Term Drift (LS8): 20ppm/kHr for demanding precision applications. A shutdown mode n Low Dropout: 300mV allows power consumption to be reduced when the refer- n Available Output Voltage Options: 1.25V, 2.048V, 2.5V, ence is not needed. The optional output capacitor can be 3V, 3.3V, 4.096V, 5V left off when space constraints are critical. n 8-Lead MSOP and 5mm 5mm Surface Mount The LTC6652 references are offered in an 8-lead MSOP Hermetic Packages package and an 8-lead LS8 package. The LS8 is a 5mm a 5mm surface mount hermetic package that provides outstanding stability. n Automotive Control and Monitoring L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear n High Temperature Industrial Technology Corporation.
