LM4040C25IDCKR Datasheet

Voltage & Current References


The LM4040C25IDCKR series of shunt voltage references are versatile, easy-to-use references that cater to a vast array of applications. The 2-pin fixed-output device requires no external capacitors for operation and is stable with all capacitive loads. Additionally, the reference offers low dynamic impedance, low noise, and low temperature coefficient to ensure a stable output voltage over a wide range of operating currents and temperatures. The LM4040C25IDCKR uses fuse and Zener-zap reverse breakdown voltage trim during wafer sort to offer four output voltage tolerances, ranging from 0.1% (max) for the A grade to 1% (max) for the D grade. Thus, a great deal of flexibility is offered to designers in choosing the best cost-to-performance ratio for their applications. LM4040C25IDCKR Features • Fixed Output Voltages of 2.048 V, 2.5 V, 3 V, 4.096 V, 5 V, 8.192 V, and 10 V• Tight Output Tolerances and Low Temperature Coefficient – Max 0.1%, 100 ppm/°C – A Grade – Max 0.2%, 100 ppm/°C – B Grade – Max 0.5%, 100 ppm/°C – C Grade – Max 1.0%, 150 ppm/°C – D Grade• Low Output Noise…35 μVRMS Typ• Wide Operating Current Range…45 μA Typ to 15 mA• Stable With All Capacitive Loads; No Output Capacitor Required• Available in Extended Temperature Range…–40°C to 125°C LM4040C25IDCKR Applications • Data-Acquisition Systems• Power Supplies and Power-Supply Monitors• Instrumentation and Test Equipment• Process Controls• Precision Audio• Automotive Electronics• Energy Management• Battery-Powered Equipment
