Built-in AD584- Chip, accuracy and stability. Single-button operation reference voltage output. Same port can output reference voltage: 2.5v, 7.5v, 5v, 10v. Single-button operation reference voltage output. Easy to use, with , more easy to control. Feature - Color: As Shown. - Material: PCB+Electronic Component. - Size: 5.5 x 5.5 x 1cm. - 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. Input voltage range of 4.5 V to 30 V. - The device uses wafer 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 (DAC) / analog to digital (ADC) converter reference voltage source, and its performance is usually better than 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 in programming its short resistance will affect the output voltage, in order to reduce the short-circuit resistance, two terminals in parallel. Alternative terminal are more reliable and flexible, short-circuit resistance can be smaller. - Temperature coefficient: 5 ppm / ° C (maximum, 0 ° C to 70 ° C, AD584L) 15 ppm / ° C (maximum, -55 ° C to + 125 ° C, AD584T). - Power Consumption: Static : 1 mA (max), low quiescent is 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 operating temperature range of 0 ° C to + 70 ° C, AD584S / T, with -55 ° C to + 125 ° C. - The external power supply interface, you need more than 11V DC voltage. - The reference voltage output interface with copper 2mm test socket for easy into the pen multimeter to measure or calibrate other instruments. - Before detect multimeter and board warm-up at 30 minutes at room temperature , to ensure that the detection accuracy.
