description
The TLV247x is a family of CMOS rail-to-rail input/output operational amplifiers that establishes a new
performance point for supply current versus ac performance. These devices consume just 600 µA/channel
while offering 2.8 MHz of gain-bandwidth product. Along with increased ac performance, the amplifier provides
high output drive capability, solving a major shortcoming of older micropower operational amplifiers. The
TLV247x can swing to within 180 mV of each supply rail while driving a 10-mA load. For non-RRO applications,
the TLV247x can supply ±35 mA at 500 mV off the rail. Both the inputs and outputs swing rail-to-rail for increased
dynamic range in low-voltage applications. This performance makes the TLV247x family ideal for sensor
interface, portable medical equipment, and other data acquisition circuits.
The family is fully specified at 3 V and 5 V across the automotive temperature range (− 40°C to 125°C).

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 34. 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 36).

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.

circuit layout considerations
To achieve the levels of high performance of the TLV247x, follow proper printed-circuit board design techniques.
A general set of guidelines is given in the following.
D Ground 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.
D Proper 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.
D Sockets − Sockets can be used but are not recommended. The additional lead inductance in the socket pins
often leads to stability problems. Surface-mount packages soldered directly to the printed-circuit board is
the best implementation.
D Short 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.
D Surface-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.

general PowerPAD design considerations
The TLV247x is available in a thermally-enhanced PowerPAD family of packages. These packages are
constructed using a downset leadframe upon which the die is mounted [see Figure 38(a) and Figure 38(b)]. This
arrangement results in the lead frame being exposed as a thermal pad on the underside of the package [see
Figure 38(c)]. Because this thermal pad has direct thermal contact with the die, excellent thermal performance
can be achieved by providing a good thermal path away from the thermal pad.
The PowerPAD package allows for both assembly and thermal management in one manufacturing operation.
During the surface-mount solder operation (when the leads are being soldered), the thermal pad can also be
soldered to a copper area underneath the package. Through the use of thermal paths within this copper area,
heat can be conducted away from the package into either a ground plane or other heat dissipating device.
The PowerPAD package represents a breakthrough in combining the small area and ease of assembly of
surface mount with the, heretofore, awkward mechanical methods of heatsinking.

general PowerPAD design considerations (continued)
1. Prepare the PCB with a top side etch pattern as shown in Figure 39. There should be etch for the leads as
well as etch for the thermal pad.
2. Place five holes (dual) or nine holes (quad) in the area of the thermal pad. These holes should be 13 mils
in diameter. Keep them small so that solder wicking through the holes is not a problem during reflow.
3. Additional vias may be placed anywhere along the thermal plane outside of the thermal pad area. This helps
dissipate the heat generated by the TLV247x IC. These additional vias may be larger than the 13-mil
diameter vias directly under the thermal pad. They can be larger because they are not in the thermal pad
area to be soldered so that wicking is not a problem.
4. Connect all holes to the internal ground plane.
5. When connecting these holes to the ground plane, do not use the typical web or spoke via connection
methodology. Web connections have a high thermal resistance connection that is useful for slowing the heat
transfer during soldering operations. This makes the soldering of vias that have plane connections easier.
In this application, however, low thermal resistance is desired for the most efficient heat transfer. Therefore,
the holes under the TLV247x PowerPAD package should make their connection to the internal ground plane
with a complete connection around the entire circumference of the plated-through hole.
6. The top-side solder mask should leave the terminals of the package and the thermal pad area with its five
holes (dual) or nine holes (quad) exposed. The bottom-side solder mask should cover the five or nine holes
of the thermal pad area. This prevents solder from being pulled away from the thermal pad area during the
reflow process.
7. Apply solder paste to the exposed thermal pad area and all of the IC terminals.
8. With these preparatory steps in place, the TLV247x IC is simply placed in position and run through the solder
reflow operation as any standard surface-mount component. This results in a part that is properly installed.

The next consideration is the package constraints. The two sources of heat within an amplifier are quiescent
power and output power. The designer should never forget about the quiescent heat generated within the
device, especially multi-amplifier devices. Because these devices have linear output stages (Class A-B), most
of the heat dissipation is at low output voltages with high output currents. Figure 41 to Figure 46 show this effect,
along with the quiescent heat, with an ambient air temperature of 70°C and 125°C. When using VDD = 3 V, there
is generally not a heat problem with an ambient air temperature of 70°C. But, when using VDD = 5 V, the
packages are severely limited in the amount of heat it can dissipate. The other key factor when looking at these
graphs is how the devices are mounted on the PCB. The PowerPAD devices are extremely useful for heat
dissipation. But, the device should always be soldered to a copper plane to fully use the heat dissipation
properties of the PowerPAD. The SOIC package, on the other hand, is highly dependent on how it is mounted
on the PCB. As more trace and copper area is placed around the device, θJA decreases and the heat dissipation
capability increases. The currents and voltages shown in these graphs are for the total package. For the dual
or quad amplifier packages, the sum of the RMS output currents and voltages should be used to choose the
proper package.

APPLICATION INFORMATION
macromodel information
Macromodel information provided was derived using Microsim Parts, the model generation software used
with Microsim PSpice. The Boyle macromodel (see Note 1) and subcircuit in Figure 47 are generated using
the TLV247x typical electrical and operating characteristics at TA = 25°C. Using this information, output
simulations of the following key parameters can be generated to a tolerance of 20% (in most cases):
