Damn! I knew it was too good to be true.  Oh well, the CCD chip needs

When you see "rail to rail" in op-amp descriptions it's a marketing term
and may not be what you expect, check the data sheets. As an example,
the TLV2370's definition of rail to rail is 0.1V to 4.9V @ VCC = 5V and
25degC (See VOH and VOL specs).
