This measured voltage reference source with stable performance, easy to use, suitable and necessary for electronic enthusiasts, electronic developers, designers, and electronic instrument maintenance. It can provide accurate reference voltage 5V and 10V, is the best partner of amateur DIYer , and HQX.

Brief Introduction:

AD588BQ With a high performance single chip, the new one price is over one hundred RMB

Basic accuracy: ±0.03% (±3mV), After adjustment and compensation for ±0.002%

Long time offset: 15ppm / 1000 hour, concentrated in the first year.

Temperature: 1.5ppm /°C,  -25℃-+85℃

The maximum output current: 10mA

The output noise: <6mV RMS

Load regulation: High load to 10mA, <±50μV / mA

Power regulation: <200μV / V

The minimum power supply: 12V AC, The current loss: 60mA

Kelvin Output connection.


AD588 as above diagram, including: pipe buried zener, constant current source, precision film resistors, four operational amplifier unit.

Constant current source driver 6.5V zener diode consists of internal reference, operational amplifier A1 and resistance R1, R2 circuit composition of the boost circuit, 10V output voltage to 6 feet (Vhigh). And provide GAIN ADJ for fine adjustment of the output of 10V.

The operational amplifier A2's role is to ensure that the level of precision, to ensure the system Level and Vlow always a potential always .

   A3, A4 is the output buffer, can output 10ma drive current and provides Kelvin connection mode.

   Resistance R4, R5 is a pair of matched 10K thin film resistor, 10V precision separate to 5V

   The 12 foot balance adjustment, connected to the R6, used to accurately adjust of the pressure of 5V.

    NOISE REDUCTION Pin (7) on the low level is connected with a capacitor, consisting of low pass filter. It can reduce the effect of Zener noise on the output.

    AD588 is very complex reference IC, provides programmable output , so that play can be very flexible.
