Amplifier AMP8 (In Stock)
$118USD
8 channels instrumentation amplifier. Can be used as signal conditioning for bridge sensors such as load cell, pressure
sensor and thermocouple sensor. 30% off if buy with iUSBDAQ data acquisition module.
AMP8 has 8 channel amplifiers with isolated outputs. It has 7 gain levels for selection,
showed as below:
6, 11, 51, 101, 201.4, 501, 1001
Please specify the gain values when purchasing, each channel can have different gain.
The default out of factory gain will be 201.4 if no specification from customer.
There is a switch on board for selecting the reference voltage. As show at below image
If this switch is at VREF position, it can shift amplified voltage to
higher level, that is the final output voltage will be Vin*G+1.65V. This is suitable for bipolar
signal, it shifts negative voltage to higher than 0V. This range voltage can then be
measured by iUSBDAQ data acquisition modules. If the input signal is unipolar signal, the
reference switch should be at GND, the relationship between input voltage and gain level
is: Vin*G<4.096V
If input voltage is bipolar, switch the reference to VREF, the relationship between input
voltage and gain level is:
2.446V>Vin*G>-1.65V
Connections:The outputs of the amplifiers can plug directly into iUSBDAQ USB data acquisition modules' pin1 - pin13. The amplifier's
output side pin order is: +5V, GND, AI0, AI1, AGND, AI2, AI3, AGND, AI4, AI5, AGND, AI6, AI7.
Input side: connecting the bridge type sensors such as load cell. Every 4 pins are a group, each group has pins 3.3V,V+,V-,GND.
3.3V is a reference voltage. Can be used as power supply to sensors.
Below diagram shows how to connect bridge type sensor to AMP:
