DESCRIPTION
The TLV27Lx single supply operational amplifiers
provide rail-to-rail output capability. The TLV27Lx takes
the minimum operating supply voltage down to 2.7 V
over the extended industrial temperature range, while
adding the rail-to-rail output swing feature. The
TLV27Lx also provides 160-kHz bandwidth from only
7 μA. The maximum recommended supply voltage is
16 V, which allows the devices to be operated from
(±8-V supplies down to ±1.35 V) two rechargeable cells.
The rail-to-rail outputs make the TLV27Lx good
upgrades for the TLC27Lx family—offering more
bandwidth at a lower quiescent current. The TLV27Lx
offset voltage is equal to that of the TLC27LxA variant.
Their cost effectiveness makes them a good alternative
to the TLC/V225x, where offset and noise are not of
premium importance.
The TLV27L1/2 are available in the commercial
temperature range to enable easy migration from the
equivalent TLC27Lx. The TLV27L1 is not available with
the power saving/performance boosting programmable
pin 8.
The TLV27L1 is available in the small SOT-23 package
—something the TLC27(L)1 was not—enabling
performance boosting in a smaller package. The
TLV27L2 is available in the 3mm x 5mm MSOP,
providing PCB area savings over the 8-pin SOIC and
8-pin TSSOP.
