Different amplifiers – Pros and Cons
Single ended (to ground) amplifiers
Cost effective and small
l
High bandwidth
l
Easy to use with probes
l
Ground problems, no safety, no CMR, no CMV
l
Single ended isolated amplifier – unbalanced differential
Can do differential measurements
l
Expensive and large
l
Difficult to use with probes
l
Limited CMRR, best CMV
l
Avoids ground loops, high safety
l
Differential amplifier (with common ground)
Widely used in DAQ
l
Good CMRR, limited CMV
l
No (safety) isolation, potential ground loops will remain present
l
Differential amplifier with isolated common
Save
