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 () or 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 will 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 or Celsius (maximum, 0 Celsius to 70 Celsius, AD584L) 15 ppm or Celsius (maximum, -55 Celsius to and 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 or K or L rated operating temperature range of 0 Celsius to and 70 Celsius, AD584S or T, with -55 Celsius to and 125 Celsius. The external power supply interface, you need more than 11V The reference voltage output interface with copper 2mm test socket for easy card into the pen multimeter to measure or calibrate other instruments. Each board at the factory to be detected with Aglient 6 digit multimeter, and marked with the output voltage, user-friendly. Before detect multimeter and board warm-up at least 30 minutes at room temperature 25 degrees, to that the detection accuracy. The following are six and a half Agilent multimeter measured 2.5V voltage output effect,2.49978V and standard error is small. Colour: yellow Material: metal Package Contents: 1 x Reference Module (different batches, some parts may be different in color, which will not affect the use) Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is 1-3cm.
