Multiduino turns an Arduino Nano into a Swiss Army knife of portable hacking. It can function as an analog multimeter to measure resistance, voltage drop, and continuity. It can also produce PWM signals, read from sensors, do basic calculator functions, and display the health of its rechargeabl...
Completely manages all timekeeping functions, Uses standard 32.768KHz watch crystal Low power operation extends battery life, low timekeeping current (400nA at 2V) Standard serial port interfaces with most microcontrollers Single-byte or multiple-byte (burst mode) data transfer for read or...
The AD8251 functions as a gain stage which improves SNR for small-amplitude signals by boosting their amplitude to more closely fill the ±VREF range at the input to the AD7982. Ideally, if the system gain increases by a factor of G, the SNR (in dB) of the input signal improves by ...
Another PGIA AFE solution is shown in Figure 16, which uses two stages to decrease the noise from the amplifier. This circuit provides various gain options by using different LT5400-X components. It allows users to configure different gains based on specific requirements. When mux’...
Usage is simple. Power the sensor with 2.7-60V to VCC, and connect V+ to the high side of your power supply, then connect V- to your grounded load. Then, use a multimeter to measure the voltage output; that's it!Technical Details Revision History: As of ...
1.1.3 Relay Drive Outputs Multifunction protection relays and RTUs also include relay outputs. This relay output uses electromechanical relay switching to convey the status of particular incidents, especially for the interlocking of protection relays and the circuit breaker system. Relay outputs can ...
3.5 Tiva C Series LaunchPad Interface This reference design uses the Tiva C Series 32-bit CPU LaunchPad to measure and transfer the data to a PC-based GUI through a USB interface. The PGA output is connected to the 12-bit ADC of Tiva LaunchPad. The gain and the channel selection for ...
