DESCRIPTION
The TLV238x single supply operational amplifiers
provide rail-to-rail input and output capability. The
TLV238x 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 TLV238x 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 combination of rail-to-rail inputs and outputs make
them good upgrades for the TLC27Lx family—offering
more bandwidth at a lower quiescent current. The offset
voltage is lower than the TLC27LxA variant.
To maintain cost effectiveness the TLV2381/2 are only
available in the extended industrial temperature range.
This means that one device can be used in a wide range
of applications that include PDAs as well as automotive
sensor interface.
All members are available in SOIC, with the singles in
the small SOT-23 package, duals in the MSOP.
