How do you select and apply an instrumentation amplifier for sensor interfaces?

Instrumentation amplifier selection: input characteristics (high impedance >1 GOhm, low bias current for high-impedance sources), CMRR (>100 dB for noisy environments), gain accuracy and stability (0.01-0.1% for precision), bandwidth (adequate for signal, not excessive to reduce noise), noise (low voltage noise for small signals), and offset drift (important for DC measurements). Application considerations: gain setting (single resistor typically), reference voltage for level shifting, power supply rejection, and input protection. Common applications: strain gauges, thermocouples, RTDs, and low-level sensors where accurate differential measurement in noise is required.
