7.3.2 Common-Mode Input Range Includes Ground

The input common-mode voltage range of the LM290xLV family extends to the negative supply rail and within 1 V below the positive rail for the full supply voltage range of 2.7 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, and significant performance degradation occurs while this pair is operational. TI recommends limiting any voltage applied at the inputs to at least 1 V below the positive supply rail (V+) to ensure that the op amp conforms to the specifications detailed in the section.
