INL integral nonlinearity—a measure in LSB of the worst-case deviation from
the ideal A/D or D/A transfer characteristic of the analog I/O circuitry
input bias current the current that flows into the inputs of a circuit
input impedance the resistance and capacitance between the input terminals of a circuit
input offset current the difference in the input bias currents of the two inputs of an
instrumentation amplifier
instrumentation
amplifier a circuit whose output voltage with respect to ground is proportional to the
difference between the voltages at its two high impedance inputs
interrupt a computer signal indicating that the CPU should suspend its current task
to service a designated activity
