NOTE:

∗ Specification is same as INA321E.

(1) Does not include errors from external gain setting resistors.

(2) Output voltage swings are measured between the output and power-supply rails.

(3) See typical characteristic Percent Overshoot vs Load Capacitance.

(4) See typical characteristic Shutdown Voltage vs Supply Voltage.

(5) Output does not swing to positive rail if gain is less than 10.
