EC Buying AD620 High Accuracy Low Power Programmable Instrumentation Amplifier Module Voltage Amplifier Module Differential Amplifier Single-Ended/Differential Small Signal/Small Amplifiers Module
... range of 1 to 10,000. Ideal for portable (or remote) applications. With high accuracy, low offset voltage, and low offset drift, the AD620 is ideal for precision data acquisition systems such as electronic scales and sensor interfaces. Also features low noise, low input bias current, and low power consumption. The module has a fixed voltage output..
♥Basic Features: ✭Module Name AD620 Instrument Programmable Amplifier ✭Module size:50mm * 50mm ✭Module power supply: 5V-24V ✭Module input signal type: single-ended signal or differential signal ✭Module signal input and output range: the input signal range is within 100 microvolts of the power supply, and the output signal range is within the power supply ✭Module bandwidth: AD620: 120KHz (G=100), AD623: 800KHz (G=1), AD620/623 is lower than 50KHz at high gain, and higher than 1MHz at low gain.
♥ Other Features: ✭Module gain: When there is no solder slip, the AD620 will zoom by 10 times by default, and the AD623 will zoom by 20 times by default. During welding slip, AD620: G=1+50K/Rg, AD623: G=1+100K/Rg ✭Maximum magnification of the module: more than 2000 times (actual measurement), due to the large gain of the waveform frequency band, it is recommended to use multi-stage amplification wi....
This is the "momentary" variety of the touch sensor - touch and it turns on, release and it turns off..
Positive and negative can be used as a touch surface,can replace the traditional touch button..
Four M2 screws positioning holes for easy installation.Module can be installed in such as surface plastic, glass of non-metallic materials..
In addition to the thin paper ( non-metallic ) covering the surface of the module , as long as the correct location of the touch , you can make hidden in the walls, desktops and other parts of buttons..
The module is based on a touch-sensing IC (TTP223B) capacitive touch switch module. In the normal state, the module output low, low power consumption.
When a finger touches the corresponding position, the module output high, if not touched for 12 seconds, switch to low-power mode..
