Specification same as for INA105AM.
NOTES: (1) Connected as difference amplifier (see Figure 4). (2) Nonlinearity is the maximum peak deviation from the best-fit straight line as a percent of full-scale peak-
to-peak output. (3) 25k
resistors are ratio matched but have
±
20% absolute value. (4) Maximum input voltage without protection is 10V more than either
±
15V supply
(
±
25V). Limit I
to 1mA. (5) With zero source impedance (see “Maintaining CMR” section). (6) Referred to output in unity-gain difference configuration. Note that this
circuit has a gain of 2 for the operational amplifier’s offset voltage and noise voltage. (7) Includes effects of amplifier’s input bias and offset currents. (8) Includes effects
of amplifier’s input current noise and thermal noise contribution of resistor network.
