TLV271/TLV272 CMOS RAIL TO RAIL OUTPUT OPERATIONAL AMPLIFIERS Description Pin Assignments 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 550 A 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 +70C operating, I grade offers -40C to +125C operating.
