Maximizing the MAX1464's ADC Range- Maxim Abstract: The MAX1464 is a high-performance, multichannel, signal conditioner that uses an internal 16-bit analog-to-digital converter to convert an analog input signal to a digital value.
An on-board interface logic allows one serial interface(with a single chip select) to control up to eight cascaded devices or 32 simultaneous sampling analog input channels.
Driving the analog input of the ADC is the most difficult point to bring out the characteristics of the ADC written in the datasheet. The longer the acquisition time, the easier it is to bring out the characteristics.
High-frequency analog input OV detection and recovery for a slow-moving input. Example Data The following example data was generated with the MAX11040K EV kit.
Four of the microcontroller's six GPIOs are used to control output signals on SDA, SCL, and a single LED, and to accept one analog input.
The compact, rugged, versatile and powerful module offers several digital and analog input and output channels for signal recording and output.
Four thresholds are used in the system; selection of these thresholds is critical to maximizing the analog input range of the system, ensuring the G 100 mode is used for as much of the signal range as possible, while also preventing the ADC input from being overranged.
In the isolated ADC, there is a delta-sigma modulator which receives an analog input from the primary voltage stage. 1 bit data is output on the secondary voltage stage after 1 bit data string is galvanically isolated by the built-in photocoupler.
Case: Pressure Control In a constant pressure system that maintains stable water pressure, Analog Input Modules are used to collect data from pressure sensors. The system, having made calculation with input data, then deliver output signal by Analog Output Modules to an inverter to control the speed of the pump.
The difficulty driving the analog input of the ADC is that it is necessary to accurately fill water in this cup to the desired water level in a short time. It will be an error component by the amount of deviation, so either if it is not enough or too much, it will not work.
Note If the analog input pin is not connected to anything, the value returned by analogRead() will fluctuate based on a number of factors(e.g. the values of the other analog inputs, how close your hand is to the board, etc.).
The analog input terminal of the ADC has a switched capacitor circuit configuration in which the capacitive element can be seen through the sampling switch. The analog input value is sampled by opening and closing this switch.(Figure 3).
If the system switches from the high-gain(G 100) mode to the low-gain(G 1) mode, the system's analog input voltage would have to be reduced by almost 50% in order to revert to the high-gain mode.
It transmits and receives commands via TCP/IP and transmits and receives settings and data of A/D and D/A conversion processing from a host PC. It is a good filter of sampling frequencies and its analog input parts can be changed easily using software.
This design ensures that the analog input voltage remains ratiometric to the reference voltage and any errors in the analog input voltage due to the temperature drift and noise of the excitation current are compensated by the variation of the reference voltage.
For an ADC, the maximum SNR is a function of its number of bits(b): SNR(1.76+ 6.02b) dB An ADC's SNR is essentially the ratio of an RMS full-scale(FS) analog input to the RMS quantization error Figure 1.
Additionally, the Spyder provides an analog input for Manual Level setpoint, control inputs for Run/Stop, Auto/Manual: Tension On/Off, and E-Stop, and a 0-1 mADC meter output proportional to measured tension.
With 4 channels 0-10V analog quantity signal input, 4 channels 0-10V analog quantity signal output, can external connect all kind of analog input sensor, such as soil temperature and humidity sensor, soil PH sensors, can control frequency converter speed control, flux of proportional valve, need to analog output applications.
The Light Sensor Module provides a very simple analog output, so all you need to connect it to your Arduino or compatible board such as the Eleven is GND, 5V, and one analog input. On a 3.3V microcontroller such as Freetronics EtherDue or Arduino Due, VCC should be connected to 3.3V instead of 5V.
