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

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.

NEW PRODUCT

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.
