AD584 is an eight-pin precision voltage reference, a programmable four common output voltages: 10.000 V, 7.500 V, 5.000 V and 2.500 V. The device uses trimming technology to adjust the pin-programmable output levels and temperature coefficients, so as to obtain the most flexible single-chip, high-precision reference voltage source. AD584 is recommended as an external precision reference voltage source of 12 or 14 bit digital to analog () / analog to digital (ADC) converter reference voltage source, and its performance is usually the standard stand-alone reference. Onboard 15V battery, we know that the battery is the lowest noise so that it can output pristine, stable voltage to provide a reliable. The board has four programming terminals ,each corresponding to an output voltage, short circuit by short-circuiting the corresponding terminal block to give the corresponding voltage. Because the AD584 programming pins in programming its short resistance affect the output voltage, in order to reduce the short-circuit resistance, two terminals in parallel. Alternative switch terminal advantage are more reliable and flexible, short-circuit resistance can be smaller. Temperature coefficient: 5 ppm / Celsius (maximum, 0 Celsius to 70 Celsius, AD584L) 15 ppm / Celsius (maximum, -55 Celsius to + 125 Celsius, AD584T) Power Consumption: Static current: 1 mA (max), low quiescent current is perfect for battery-powered. Load capacity: 10 mA Operating voltage: 4.5V to 30V, note that the required operating voltage higher than the programmed output voltage Temperature range: AD584J / K / L rated operating temperature range of 0 Celsius to + 70 Celsius, AD584S / T, with -55 Celsius to + 125 Celsius. The external power supply interface, you need more than 11V DC voltage The reference voltage output interface with copper 2mm test socket for easy card into the pen multimeter to measure or calibrate other inst
