AD584 High Precision Voltage Reference Module 4-Channel Work On 2.5V/7.5V/5V/10V 4.5-30V

Description:

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. Input voltage range of 4.5 V to 30 V.

The device uses laser 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.

There are AD584J, AD584K, AD584L on the market.

AD584L is the best performance, see below, with our board is AD584L

Features:

1. onboard 15V battery, we know that the battery is the lowest noise so that it can output pristine, stable voltage to provide a reliable guarantee.

2. 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 benefits are more reliable and flexible, short-circuit resistance can be smaller.

3. Temperature coefficient: 5 ppm / ° C (maximum, 0 ° C to 70 ° C, AD584L) 15 ppm / ° C (maximum, -55 ° C to + 125 ° C, AD584T)

4. Power Consumption: Static current: 1 mA (max), low quiescent current is ideal for battery-powered.

5. Load capacity: 10 mA
