Application Information BRIDGE CONFIGURATION EXPLANATION As shown in Figure 1, the LM4901 has two internal opera- tional amplifiers. The first amplifier’s gain is externally con- figurable, while the second amplifier is internally fixed in a unity-gain, inverting configuration. The closed-loop ...
Page 13
Application Information external component combinations, consideration to compo- nent values must be used to maximize overall system qual- ity. The LM4901 is unity-gain stable which gives the designer maximum system flexibility. The LM4901 should be used in low gain configurations ...
Page 14
Application Information The LM4901 is unity-gain stable and requires no external components besides gain-setting resistors, an input coupling capacitor, and proper supply bypassing in the typical appli- cation. However closed-loop differential gain of greater than 10 is required, ...
