User Manual
The board uses ADI ADR03 as voltage reference,ADR03 features are as follows:
-
Less than the 3ppm/℃ temperature coefficient,which determines the
effect of temperature changes on the ADC data collection,3ppm/that is
one degree of change can cause voltage reference three out of 10,000
changes,so there is a high quality voltage reference is so important.
-
Less than ± 0.1% initialization accuracy error is the output voltage
and the reference value,it determines a number of product consistency.
-
Noise less than 10uVp-p,the noise voltage reference output will also
directly affect the accuracy of the ADC,the noise is within 0.1Hz to
10Hz,added 0.1-10Hz after a low pass filter effectively reduces
low-frequency noise,the following figure:
Product features:
1.A0-A7 ADC,8 input channels can be easily configured for differential and single-ended inputs.
2.Low temperature drift and low noise Vishay wafer metal film resistors.
3.Input filter capacitor (104),one per channel.
4.High speed LDO with low noise,high PSRR,low quiescent current.
5.High frequency digital signal decay resistance,isolation external high frequency noise.
6.ADR03
2.5V voltage reference,OPA350 0.1Hz~10Hz low pass filter circuit is
composed of cache memory,and large-capacity tantalum capacitors and
ceramic capacitor in parallel with wafers and low-noise metal film
resistor,effectively suppressing low-frequency noise.
7.Tantalum capacitor 100uF bulk filtering,and composed of inductors LC filter circuit,making power more pure.
8.Analog signal and digital signal wiring separately.
9.Added GND,2.5V,3.3V,test points,and make it easier to debug the circuit.
Speed: the max 30Ksps.
Power supply: single 5V
Package List:
- 1 x Data Acquisition Module
