Description

General part information

LT6657 Series

The LT6657 is a precision voltage reference that combines robust operating characteristics with extremely low drift and low noise. With advanced curvature compensation, this bandgap reference achieves 1.5ppm/°C drift with predictable temperature behavior, and an initial voltage accuracy of 0.1%. It also offers 0.5ppmP-Pnoise and very low temperature cycling hysteresis.The LT6657 is a low dropout reference that can be powered from as little as 50mV above the output voltage, up to 40V. The buffered output supports ±10mA of output drive with low output impedance and precise load regulation. The high sink current capability allows operation as a negative voltage reference with the same precision as a positive reference. This part is safe under reverse battery conditions, and includes current protection when the output is short-circuited and thermal shutdown for overload conditions. A shutdown is included to allow power reduction while enabling a quick turn-on.The LT6657 is fully specified over the temperature range of –40°C to 125°C. It is available in the 8-lead MSOP package.ApplicationsHigh Temperature IndustrialHigh Resolution Data Acquisition SystemsInstrumentation and Process ControlAutomotive Control and MonitoringMedical EquipmentShunt and Negative Voltage References
