6.3.2 Input Common Mode Range

The input common-mode voltage range of the LMV3xxA family extends 100 mV beyond the negative supply rail and within 1 V below the positive rail for the full supply voltage range of 2.5 V to 5.5 V. This performance is achieved with a P-channel differential pair, as shown in the Functional Block Diagram. Additionally, a complementary N-channel differential pair has been included in parallel to eliminate issues with phase reversal that are common with previous generations of op amps. However, the N-channel pair is not optimized for operation. TI recommends limiting any voltages applied at the inputs to less than VCC – 1 V to ensure that the op amp conforms to the specifications detailed in the Electrical Characteristics table.
