IA
selection guide
IA — Instrumentation Amplifier
CMRR — should be higher, this will
suppress common-mode unwanted signals
The low input bias current
Low drift
Low input voltage offset
Low input voltage noise
Slew rate —select according to
application
Supply voltage range — rail to rail
range, single-supply range
Gain bandwidth — select according to
gain and bandwidth requirements of the application
Input impedance — this is usually
higher than general op-amps
Low input current noise
Price — high precision IAs are very
expensive, be aware of the application requirements against the required IA
specifications
Package size
PCB layout guidelines- usually
provide in datasheet or application notes
