WebA rail-to-rail output stage (a) has a common-emitter configuration, while a standard output stage (b) has an emitter-follower configuration. Because a bipolar transistor's V CE (SAT) depends on the current through the transistor, the output swing of a bipolar op amp depends on its load current. Webamplifier's supply rails. For example, the input common-mode voltage range of the OPA375 is shown in Table 1. The input common-mode voltage range extends to V–, the negative rail, but only extends to 1.2 V below Vs, the positive rail, meaning this is not an RRI amplifier.

Four ways to design an amplifier without a rail-to-rail op amp

WebIn addition, these devices do not phase invert when the common-mode input is driven to the supply rails. This satisfies most design requirements without paying a premium for rail-to-rail input performance. They also exhibit rail-to-rail output performance for increased dynamic range in single- or split-supply applications. WebRail-to-Rail Input Common-Mode Voltage Range (Ensured Over Temperature) Rail-to-Rail Output Swing (within 20mV of supply rail, 100KΩ load) ...
