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.

Notes: 4. Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings only; functional
operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
5. All voltage values, except differential voltages, are with respect to ground
6. For operating at high temperatures, the TLV27x must be derated to zero based on a +150°C maximum junction temperature and a thermal resistance
as below when the device is soldered to a printed circuit board, operating in a still air ambient:

Application Information
Driving a Capacitive Load
When the amplifier is configured as below, capacitive loading directly on the output can decrease the device’s phase margin leading to high
frequency ringing or oscillations. Therefore, for capacitive loads of greater than 100pF, it is recommended that a resistor be placed in series (RNULL)
with the output of the amplifier, as shown in Figure 25. A minimum value of 20 should work well for most applications.
Figure 28 Driving a Capacitive Load
Offset Voltage
The output offset voltage, (VOO) is the sum of the input offset voltage (VIO) and both input bias currents (IIB) times the corresponding gains. The
following schematic and formula can be used to calculate the output offset voltage:
Figure 29 Output Offset Voltage Model
Other Configurations
When receiving low-level signals, limiting the bandwidth of the incoming signals into the system is often required. The simplest way to accomplish
this is to place an RC filter at the non-inverting terminal of the amplifier (see Figure 30).
Figure 30. Single Pole Low Pass Filter
If even more attenuation is needed, a multiple pole filter is required. The Sallen-Key filter can be used for this task. For best results, the amplifier
should have a bandwidth that is 8 to 10 times the filter frequency bandwidth. Failure to do this can result in phase shift of the amplifier.
