LT6650HS5#TRMPBF Analog Devices

LT6650 Micropower, 400mV Reference with Rail-to-Rail Buffer Amplifier in SOT-23 DESCRIPTIO FEATURES Low Quiescent Current 5.6A (typical) The LT 6650 is a micropower, low voltage 400mV refer- Wide Supply Range: 1.4V to 18V ence. Operating with supplies from 1.4V up to 18V, the 400mV Reference 1% Maximum Accuracy Over device draws only 5.6A typical, making it ideal for low Temperature at 5V voltage systems as well as handheld instruments and Rail-to-Rail Buffer Amplifier industrial control systems. With only two resistors the 0.5% 400mV Maximum Initial Accuracy at 5V internal buffer amplifier can scale the 400mV reference to Shunt Configurable any desired value up to the supply voltage. Sinks and Sources Current The reference is postpackage-trimmed to increase the Wide Operational Range 40C to 125C output accuracy. The output can sink and source 200A Externally Adjustable Output Voltage over temperature. Quiescent power dissipation is 28W. Low Profile 1mm 5-lead SOT-23 Stability is ensured with any output capacitor of 1F or (ThinSOT) Package higher.
