LT6657AHMS8-3#PBF

LT6657 is a precision voltage reference that combines robust operating characteristics with extremely low drift and low noise. It is a low dropout reference that can be powered from as little as 50mV above the output voltage, upto 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. It is used in applications such as high temperature industrial, high resolution data acquisition systems, instrumentation and process control, automotive control and monitoring, medical equipment, shunt and negative voltage references etc.
