9.3 Feature Description
9.3.1 Unity-Gain Bandwidth
The unity-gain bandwidth is the frequency up to which an amplifier with a unity gain may be operated without
greatly distorting the signal. These devices have a 1.2-MHz unity-gain bandwidth (LM2904B-Q1).
9.3.2 Slew Rate
The slew rate is the rate at which an operational amplifier can change its output when there is a change on the
input. These devices have a 0.5-V/µs slew rate (LM2904B-Q1).
9.3.3 Input Common Mode Range
The valid common mode range is from device ground to VS – 1.5 V (VS – 2 V across temperature). Inputs may
exceed VS up to the maximum VS without device damage. At least one input must be in the valid input common-
mode range for the output to be the correct phase. If both inputs exceed the valid range, then the output phase
is undefined. If either input more than 0.3 V below V– then input current should be limited to 1 mA and the output
phase is undefined.
9.4 Device Functional Modes
The LM2904-Q1 and LM2904B-Q1 devices are powered on when the supply is connected. This device can be
operated as a single-supply operational amplifier or dual-supply amplifier, depending on the application.
