LMV324A: What is the difference between the LMV324IPWR and the LMV324AIPWR?

The LM324 is a bipolar, high-voltage opamp and requires 2 V headroom to the positive supply rail. The LMV324 was designed as a low-voltage version with a smaller headroom requirement and rail-to-rail outputs, but still uses the same bipolar architecture. The LMV324A and LM324LV are more modern CMOS versions, with smaller power consumption and other improvements. (In low-voltage applications, you often need rail-to-rail inputs, which would be supported by the TLV9004.)

For compatibility, all these devices are designed to have similar bandwidth.

Hello Michael,

Normally the A would be a different grade for offset voltage when both devices are on same data sheet.

For DBV package , the pin out is different. For other packages, same pinout. The part with A does have better offset , CMRR, DC open loop gain.
