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
A. 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.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
