The TLC2272 and TLC2274 are dual and quadruple operational amplifiers from Texas Instruments. Both devices exhibit rail-to-rail output performance for increased dynamic range in single- or split-supply applications. The TLC227x family offers 2 MHz of bandwidth and 3 V/μs of slew rate for higher-speed applications. These devices offer comparable AC performance while having better noise, input offset voltage, and power dissipation than existing CMOS operational amplifiers. The TLC227x has a noise voltage of 9 nV/√Hz, two times lower than competitive solutions.
The TLC227x family of devices, exhibiting high input impedance and low noise, is excellent for small-signal conditioning for high-impedance sources such as piezoelectric transducers. Because of the micropower dissipation levels, these devices work well in hand-held monitoring and remote-sensing applications. In addition, the rail-to-rail output feature, with single- or split-supplies, makes this family a great choice when interfacing with analog-to-digital converters (ADCs). For precision applications, the TLC227xA family is available with a maximum input offset voltage of 950 μV. This family is fully characterized at 5 V and ±5 V.
The TLC227x also make great upgrades to the TLC27x in standard designs. They offer increased output dynamic range, lower noise voltage, and lower input offset voltage. This enhanced feature set allows them to be used in a wider range of applications. For applications that require higher output drive and wider input voltage range, see the TLV2432 and TLV2442 devices.
If the design requires single amplifiers, see the TLV2211, TLV2221 and TLV2231 family. These devices are single rail-to-rail operational amplifiers in the SOT-23 package. Their small size and low power consumption make them ideal for high density, battery-powered equipment.

The TLC227x and TLC227xA family of devices feature 2-MHz bandwidth and voltage noise of 9 nV/√Hz with performance rated from 4.4 V to 16 V across an automotive temperature range (–40°C to 125°C). LinMOS suits a wide range of audio, automotive, industrial, and instrumentation applications.
The TLC227x and TLC227xA families of devices is powered on when the supply is connected. The devices may operate with single or dual supply, depending on the application. The devices are in its full performance once the supply is above the recommended value.
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.
Macromodel information provided was derived using MicroSim Parts™, the model generation software used with MicroSim PSpice™. The Boyle macromodel (1) and subcircuit in Figure 59 were generated using the TLC227x 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):
For this design example, use the parameters listed in Table 3 as the input parameters.
PARAMETER | VALUE | |
---|---|---|
VBAT | Battery Voltage | 12 V |
RSENSE | Sense Resistor | 0.1 Ω |
ILOAD | Load Current | 0 A to 10 A |
Operational Amplifier | Set in Differential configuration with Gain = 10 |
This circuit is designed for measuring the high-side current in automotive body control modules with 12-V battery or similar applications. The operational amplifier is set as differential with an external resistor network.
Equation 1 and Equation 2 are used to calculate VOUT.
In an ideal case R1 = R and R2 = Rg, and VOUT can then be calculated using Equation 3:
However, as the resistors have tolerances, they cannot be perfectly matched.
R1 = R ± ΔR1
R2 = R2 ± ΔR2
R = R ± ΔR
Rg = Rg ± ΔRg
By developing the equations and neglecting the second order, the worst case is when the tolerances add up. This is shown by Equation 5.
where
If the resistors are perfectly matched, then Tol = 0 and VOUT is calculated using Equation 6.
The highest error is from the Common mode, as shown in Equation 7.
Gain of 10, Rg / R = 10, and Tol = 1%:
Common mode error = ((4 × 0.01) / 1.1) × 12 V = 0.436 V
Gain of 10 and Tol = 0.1%:
Common mode error = 43.6 mV
The resistors were chosen from 2% batches.
R1 and R 12 kΩ
R2 and Rg 120 kΩ
Ideal Gain = 120 / 12 = 10
The measured value of the resistors:
R1 = 11.835 kΩ
R = 11.85 kΩ
R2 = 117.92 kΩ
Rg = 118.07 kΩ
