LM339A: The difference between LM339ANSR and LM339NSR

Hi Kevin,

The "A" has lower specified offset voltages.

The differences can be seen on page 7, section 7.7 in the "Electrical Characteristics for LMx39 and LMx39A" table.

For the non-A version, use the LM339 column on the left (5 mV). For the "A" version, use the LM339A column on the right (3 mV).
