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 –40°C to 125°C. 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: 2.1ppmP-P (0.1Hz to 10Hz)
mance industrial and other high temperature applications. n
100% Tested at –40°C, 25°C and 125°C
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: <2µA Maximum cellent load regulation, source and sink capability and n Thermal Hysteresis (LS8): 45ppm (–40°C to 125°C) 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 Hermetic Packages The LTC6652 references are offered in an 8-lead MSOP package and an 8-lead LS8 package.
