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.
