VCC – Supply Voltage – V
The TLV230x combines sub-micropower operational amplifier and comparator into a single package that
produces excellent micropower signal conditioning with only 1.4 μA of supply current. This combination gives
the designer more board space and reduces part counts in systems that require an operational amplifier and
comparator. The low supply current makes it an ideal choice for battery-powered portable applications where
quiescent current is the primary concern. Reverse battery protection guards the amplifier from an over-current
condition due to improper battery installation. For harsh environments, the inputs can be taken 5 V above the
positive supply rail without damage to the device.
The TLV230x’s low supply current is coupled with extremely low input bias currents enabling them to be used
with mega-ohm resistors making them ideal for portable, long active life, applications. DC accuracy is ensured
with a low typical offset voltage as low as 390 μV, CMRR of 90 dB and minimum open loop gain of 130 V/mV
at 2.7 V.
The maximum recommended supply voltage is as high as 16 V and ensured operation down to 2.5 V, with
electrical characteristics specified at 2.7 V, 5 V, and 15 V. The 2.5-V operation makes it compatible with Li-Ion
battery-powered systems and many micropower microcontrollers available today including TI’s MSP430.
All members are available in PDIP and SOIC with the duals (one op-amp and one comparator) in the small
MSOP package, and the quads (two operational amplifiers and two comparators) in the TSSOP package.

APPLICATION INFORMATION
reverse battery protection
The TLV2302/4 is protected against reverse battery voltage up to 18 V. When subjected to reverse battery
condition, the supply current is typically less than 100 nA at 25°C (inputs grounded and outputs open). This
current is determined by the leakage of six Schottky diodes and will therefore increase as the ambient
temperature increases.
When subjected to reverse battery conditions and negative voltages applied to the inputs or outputs, the input
ESD structure will turn on—this current should be limited to less than 10 mA. If the inputs or outputs are referred
to ground, rather than midrail, no extra precautions need be taken.
common-mode input range
The TLV2302/4 has rail-rail input and outputs. For common-mode inputs from –0.1 V to VCC – 0.8 V a PNP
differential pair will provide the gain.
For inputs between VCC – 0.8 V and VCC, two NPN emitter followers buffering a second PNP differential pair
provide the gain. This special combination of NPN/PNP differential pair enables the inputs to be taken 5 V above
the rails; because as the inputs go above VCC, the NPNs switch from functioning as transistors to functioning
as diodes. This will lead to an increase in input bias current. The second PNP differential pair continues to
function normally as the inputs exceed VCC.
The TLV2302/4 has a negative common-input range that exceeds ground by 100 mV. If the inputs are taken
much below this, reduced open loop gain will be observed with the ultimate possibility of phase inversion.

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 35).

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 TLV230x, follow proper printed-circuit board design techniques.
A general set of guidelines is given in the following.
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.
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.
Sockets—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.
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 will help to minimize stray capacitance at
the input of the amplifier.
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.

amplifier macromodel information
Macromodel information provided was derived using Microsim Parts ™ Release 8, the model generation
software used with Microsim PSpice ™. The Boyle macromodel (see Note 2) and subcircuit in Figure 38 are
generated using the TLV230x 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):
Maximum positive output voltage swing
