TLV2371-Q1, TLV2372-Q1, TLV2374-Q1
SGLS244B – MAY 2004 – REVISED DECEMBER 2016
TLV237x-Q1 550-µA/Channel, 3-MHz Rail-to-Rail Input and Output Operational Amplifiers
1 Features
3 Description
•
•
The TLV237x-Q1 devices are single-supply
operational amplifiers providing rail-to-rail input and
output capability. The TLV237x-Q1 takes the
minimum operating supply voltage down to 2.7 V and
up to 16 V over the extended automotive temperature
range. Therefore, the wide voltage range can support
both start-stop functionality and a connection directly
to the typical 12-V battery. The rail-to-rail capabilities
allow the device to maximize the output signal and
avoid clipping.

any level without the concern for any phase reversal.
2 Applications
•
•
•
•
•
•
The CMOS inputs enable high-impedance suitable for
engine control units (ECU), body control modules
(BCM), battery management systems (BMS), and
HEV/EV inverters. This also allows the user to draw a
lower offset voltage and maintain low power
consumption to help meet overall system needs for
quiescent current such as in infotainment or cluster,
HEV/EV, and powertrain.

8 Detailed Description
8.1 Overview
The TLV237x-Q1 single-supply operational amplifiers provide rail-to-rail input and output capability with 3-MHz
bandwidth. Consuming only 550 µA, the TLV237x-Q1 is the perfect choice for portable and battery-operated
applications. 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 rail-to-rail inputs with high input impedance
make the TLV237x-Q1 ideal for sensor signal-conditioning applications.

8.3 Feature Description
8.3.1 Rail-to-Rail Input Operation
The TLV237x-Q1 input stage consists of two differential transistor pairs, NMOS and PMOS, that operate together
to achieve rail-to-rail input operation. The transition point between these two pairs can be seen in Figure 1
through Figure 3 for a 2.7-V, 5-V, and 15-V supply. As the common-mode input voltage approaches the positive
supply rail, the input pair switches from the PMOS differential pair to the NMOS differential pair. This transition
occurs approximately 1.35 V from the positive rail and results in a change in offset voltage due to different device
characteristics between the NMOS and PMOS pairs. If the input signal to the device is large enough to swing
between both rails, this transition results in a reduction in common-mode rejection ratio (CMRR). If the input
signal does not swing between both rails, it is best to bias the signal in the region where only one input pair is
active. This is the region in Figure 1 through Figure 3 where the offset voltage varies slightly across the input
range and optimal CMRR can be achieved. This has the greatest impact when operating from a 2.7-V supply
voltage.

Feature Description (continued)
8.3.2 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, TI recommends placing a resistor in series (RNULL) with the output of the amplifier, as shown in Figure 28.
A minimum value of 20 Ω works well for most applications.

8.3.3 Offset Voltage
The output offset voltage, (VOO) is the sum of the input offset volt age (VIO) and both input bias currents (IIB)
times the corresponding gains. The schematic and formula in Figure 29 can be used to calculate the output
offset voltage.

8.3.4 General 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 noninverting terminal of the amplifier (see
Figure 30).

Figure 30. Single-Pole Low-Pass Filter
If even more attenuation is required, a multiple pole filter is required. The Sallen-Key filter can be used for this
task (see Figure 31). For best results, the amplifier must 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.

9 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
9.1 Application Information
When designing for low power, choose system components carefully. To minimize current consumption, select
large-value resistors. Any resistors can react with stray capacitance in the circuit and the input capacitance of the
operational amplifier. These parasitic RC combinations can affect the stability of the overall system. Use of a
feedback capacitor assures stability and limits overshoot or gain peaking.
9.2 Typical Applications
9.2.1 High-Side Current Monitor
The TLV237x-Q1 is rail-to-rail input and output capability and up to 16-V supply voltage. That makes the device
suitable in body control model applications and more specific high-side current sensing. The input common mode
is at the supply voltage so there is no limitation in differential gain.

9.2.2 Inverting Amplifier
A typical application for an operational amplifier is an inverting amplifier, as shown in Figure 34. An inverting
amplifier takes a positive voltage on the input and outputs a signal inverted to the input, making a negative
voltage of the same magnitude. In the same manner, the amplifier also makes negative input voltages positive on
the output. In addition, amplification can be added by selecting the input resistor RI and the feedback resistor RF.

9.2.3 Design Requirements
The supply voltage must be chosen to be larger than the input voltage range and the desired output range. The
limits of the input common-mode range (VCM) and the output voltage swing to the rails (VO) must also be
considered. For instance, this application scales a signal of ±0.5 V (1 V) to ±1.8 V (3.6 V). Setting the supply at
±2.5 V is sufficient to accommodate this application.

When the desired gain is determined, choose a value for RI or RF. Choosing a value in the kΩ range is desirable
for general-purpose applications because the amplifier circuit uses currents in the milliamp range. This milliamp
current range ensures the device does not draw too much current. The trade-off is that large resistors (hundreds
of kΩ) draw the smallest current but generate the highest noise. Small resistors (hundreds of Ω) generate low
noise but draw high current. This example uses 10 kΩ for RI, meaning 36 kΩ is used for RF. These values are
determined by Equation 15.

10 Power Supply Recommendations
The TLV237x-Q1 family is specified for operation from 2.7 V to 15 V (±1.35 V to ±7.5 V); many specifications
apply from –40°C to 125°C. The Typical Characteristics presents parameters that can exhibit significant variance
with regard to operating voltage or temperature.
CAUTION
Supply voltages larger than 16 V can permanently damage the device (see the
Absolute Maximum Ratings).
Place 0.1-µF bypass capacitors close to the power-supply pins to reduce errors coupling in from noisy or highimpedance power supplies. For more detailed information on bypass capacitor placement (see Layout).

11 Layout
11.1 Layout Guidelines
To achieve the levels of high performance of the TLV237x-Q1, follow proper printed-circuit board design
techniques. The following is a general set of guidelines:
• Ground planes: TI highly recommends 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 capacitor among several amplifiers
depending on the application, but a 0.1-µF ceramic capacitor must always be used on the supply terminal of
every amplifier. In addition, the 0.1-µF capacitor must 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 must 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
often leads to stability problems. Surface-mount packages soldered directly to the printed-circuit board is the
best implementation.
• Short trace runs or compact part placements: Optimum high performance is achieved when stray series
inductance has been minimized. To realize this, the circuit layout must be made as compact as possible,
thereby minimizing the length of all trace runs. Pay particular attention to the inverting input of the amplifier.
Its length must be kept as short as possible. This helps 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, TI recommends that the lead lengths be kept as
short as possible.
