TLV271/TLV272

CMOS RAIL TO RAIL OUTPUT OPERATIONAL AMPLIFIERS

Description

The TLV27x provides a higher performance alternative to the TLC27x
series of op-amps. These devices take the minimum operating supply
voltage down to 2.7V over the extended industrial temperature range
while adding the rail-to-rail output swing feature.

This makes it an ideal alternative to the TLC27x family for
applications where rail-to-rail output swings are essential. The
TLV27x also provides 2-MHz bandwidth from only 550μA supply
current.

The TLV27x is fully specified for 5V and ±5V supplies. The maximum
recommended supply voltage is 16V. The devices can be operated
from a variety of rechargeable cells from ±8V down to ±1.35V.

The CMOS inputs enable use in high-impedance sensor interfaces,
with the lower voltage operation making an attractive alternative for
the TLC27x in battery-powered applications.

The 2.7-V operation makes it compatible with Li-Ion powered systems
and the operating supply voltage range of many micro-power micro-
controllers available today.

All parts are available in SOIC packaging; the TLV271 is additionally
available in the SOT25 package. Two temperature grades are
available for the parts; C grade offers 0 to +70°C operating, I grade
offers -40°C to +125°C operating.
