DIdeal Upgrade for TLC27x Family
description
The TLV27x takes the minimum operating supply voltage down to 2.7 V over the extended automotive
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 3-MHz
bandwidth from only 550 µA.
Like the TLC27x, the TLV27x is fully specified for 5-V and ±5-V supplies. The maximum recommended supply
voltage is 16 V, which allows the devices to be operated from a variety of rechargeable cells (±8 V supplies down
to ±1.35 V).
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 micropower microcontrollers available today including Texas Instruments MSP430.

APPLICATION INFORMATION
driving a capacitive load
When the amplifier is configured in this manner, capacitive loading directly on the output decreases the device’s
phase margin leading to high frequency ringing or oscillations. Therefore, for capacitive loads of greater than
10 pF, 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 Ω should work well for most applications.

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 noninverting terminal of the amplifier
(see Figure 27).

If even more attenuation is needed, a multiple pole filter is required. The Sallen-Key filter can be used for this
task. For the 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.

APPLICATION INFORMATION
circuit layout considerations
To achieve the levels of high performance of the TLV27x, follow proper printed-circuit board design techniques.
A general set of guidelines is given in the following.
DGround planes—It is highly recommended that a ground plane be used on the board to provide all
components with a low inductive ground connection. However, in the areas of the amplifier inputs and
output, the ground plane can be removed to minimize the stray capacitance.
DProper power supply decoupling—Use a 6.8-µF tantalum capacitor in parallel with a 0.1-µF ceramic
capacitor on each supply terminal. It may be possible to share the tantalum among several amplifiers
depending on the application, but a 0.1-µF ceramic capacitor should always be used on the supply terminal
of every amplifier. In addition, the 0.1-µF capacitor should be placed as close as possible to the supply
terminal. As this distance increases, the inductance in the connecting trace makes the capacitor less
effective. The designer should strive for distances of less than 0.1 inches between the device power
terminals and the ceramic capacitors.
DSockets—Sockets can be used but are not recommended. The additional lead inductance in the socket pins
will often lead to stability problems. Surface-mount packages soldered directly to the printed-circuit board
is the best implementation.
DShort trace runs/compact part placements—Optimum high performance is achieved when stray series
inductance has been minimized. To realize this, the circuit layout should be made as compact as possible,
thereby minimizing the length of all trace runs. Particular attention should be paid to the inverting input of
the amplifier. Its length should be kept as short as possible. This helps to minimize stray capacitance at the
input of the amplifier.
DSurface-mount passive components—Using surface-mount passive components is recommended for high
performance amplifier circuits for several reasons. First, because of the extremely low lead inductance of
surface-mount components, the problem with stray series inductance is greatly reduced. Second, the small
size of surface-mount components naturally leads to a more compact layout thereby minimizing both stray
inductance and capacitance. If leaded components are used, it is recommended that the lead lengths be
kept as short as possible.

applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components which meet ISO/TS16949 requirements, mainly for automotive use. Components which
have not been so designated are neither designed nor intended for automotive use; and TI will not be responsible for any failure of such
components to meet such requirements.
