Note 1: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to any
Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime.
Note 2: The op amp supplies must be established simultaneously, with, or before, the application of any input signals.
Note 3: The inputs are protected by ESD protection diodes to each power supply. If the input extends more than 500mV beyond the power supply, the input current should be limited to less than 10mA.
Note 4: A heat sink may be required to keep the junction temperature below the absolute maximum. This depends on the power supply voltage and how many
amplifiers are shorted. Thermal resistance varies with the amount of PC board metal connected to the package. The specified values are for short traces
connected to the leads.

Pin Functions
-IN: Inverting Input of the Amplifier. +IN: Non-Inverting Input of Amplifier.
OUT: Amplifier Output. The voltage range extends to within mV of each supply rail.
V+ or +Vs: Positive Power Supply. Typically the voltage is from 2.2V to 5.5V. Split supplies are possible as long as the voltage between V+ and V– is between 2.2V and 5.5V. A bypass capacitor of 0.1μF as close to the part as
possible should be used between power supply pins or between supply pins and ground.
V- or -Vs: Negative Power Supply. It is normally tied to ground. It can also be tied to a voltage other than ground as long as the voltage between V+ and V– is from 2.2V to 5.5V. If it is not connected to ground, bypass it with a capacitor of 0.1μF as close to the part as
possible.
Operation
TP2411系列运算放大器可在单电源电压（2.2 V至5.5 V）或分电源电压（±1.1 V至±2.75 V）上工作，从而使其 通用性强且易于使用。 电源引脚应具有本地旁路陶瓷电容器（通常为0.001 F至0.1 F）。 这些放大器的额定电压 范围为+2.2 V至+5.5 V，并在–40°C至+ 125°C的扩展温度范围内。 典型特性中列出了可能随工作电压或温度而 变化的参数。
Applications Information
Input ESD Diode Protection
TP2411的所有引脚上均集成了内部静电放电（ESD）保护电路。 对于输入和输出引脚，此保护主要由连接在输入和电源引脚之间的电流控制二极管组成。 这些ESD保护二极管还提供电路输入过驱动保护，只要电流被限制在绝对最大额定值表中规定的10 mA。 许多输入信号固有地被限制为小于10 mA的电流。 因此，不需要限制电阻。 图1显示了如何将串联输入电阻（RS）添加到驱动输入以限制输入电流。 添加的电阻会在放大器输入端产生热噪声，在对噪声敏感的应用中，该值应保持最小。

PHASE REVERSAL
The TP2411 op amps are designed to be immune to phase reversal when the input pins exceed the supply voltages, therefore providing further in-system stability and predictability. Figure 2 shows the input voltage exceeding the supply voltage without any phase reversal.
Figure 2. No Phase Reversal
EMI SUSCEPTIBILITY AND INPUT FILTERING
Operational amplifiers vary in susceptibility to electromagnetic interference (EMI). If conducted EMI enters the device, the dc offset observed at the amplifier output may shift from the nominal value while EMI is present. This shift is a result of signal rectification associated with the internal semiconductor junctions. While all operational amplifier pin functions can be affected by EMI, the input pins are likely to be the most susceptible. The TP2411 operational amplifier family incorporates an internal input low-pass filter that reduces the amplifier response to EMI. Both common-mode and differential mode filtering are provided by the input filter. The filter is designed for a cutoff frequency of approximately 500 MHz (–3 dB), with a roll-off of 20 dB per decade.

PCB Surface Leakage
在低输入偏置电流至关重要的应用中，需要考虑印刷电路板（PCB）表面泄漏的影响。 表面泄漏是由板上的湿气，灰尘或其他污染引起的。 在低湿度条件下，附近走线之间的典型电阻为1012Ω。 5V的差异将导致5pA的电流流过，这大于TP2411 / 2412/2414 OPA在+ 27°C时的输入偏置电流（典型值为±3pA）。 建议使用多层PCB布局，并在PCB表面下布线OPA的-IN和+ IN信号。 减少表面泄漏的有效方法是在敏感引脚（或走线）周围使用保护环。 保护环的偏置电压与敏感引脚的偏置电压相同。图1显示了这种类型的布局示例，用于反向增益应用。 1. For Non-Inverting Gain and Unity-Gain Buffer:
a) Connect the non-inverting pin (VIN+) to the input with a wire that does not touch the PCB surface.
b) Connect the guard ring to the inverting input pin (VIN–). This biases the guard ring to the Common Mode input voltage.
2. For Inverting Gain and Trans-impedance Gain Amplifiers (convert current to voltage, such as photo detectors):
a
) Connect the guard ring to the non-inverting input pin (VIN+). This biases the guard ring to the same reference voltage as the op-amp (e.g., VDD/2 or ground).
b) Connect the inverting pin (VIN–) to the input with a wire that does not touch the PCB surface.
Guard Ring VIN+ VIN- +VS
Figure 4 The Layout of Guard Ring
Power Supply Layout and Bypass
The TP2411/2412/2412 OPA’s power supply pin (VDD for single-supply) should have a local bypass capacitor (i.e., 0.01μF to 0.1μF) within 2mm for good high frequency performance. It can also use a bulk capacitor (i.e., 1μF or larger) within 100mm to provide large, slow currents. This bulk capacitor can be shared with other analog parts.
Ground layout improves performance by decreasing the amount of stray capacitance and noise at the OPA’s inputs a
nd outputs. To decrease stray capacitance, minimize PC board lengths and resistor leads, and place external c
omponents as close to the op amps’ pins as possible. Proper Board Layout
为了确保在PCB级别上具有最佳性能，必须在电路板布局的设计中务必小心。为避免泄漏电流，电路 板表面应保持清洁且无湿气。涂层表面可防止水分积聚，并有助于降低电路板上的寄生电阻。保持电源走线短 并适当旁路电源，可将由于输出电流变化而引起的电源干扰降至最低，例如将ac信号驱动为重负载时。旁 路电容器应尽可能靠近器件的电源引脚连接。杂散电容是放大器输出和输入的一个问题。建议将信号走线 与电源线保持至少5mm的距离，以最大程度地减少耦合.PCB上的温度变化可能会导致焊点和其他异种金属 接触点的Seebeck电压不匹配，从而导致热电压错误。为了最大程度地减少这些热电偶效应，请对电阻器进 行定向，使热源对两端均等地加热。输入信号路径应包含匹配数量和类型的组件，并在可能的情况下匹配热 电偶结的数量和类型。例如，可以使用零值电阻器之类的虚拟组件来匹配相反输入路径中的真实电阻器。匹 配组件应紧邻放置，并以相同的方式定向。确保导线的长度相等，以使热传导达到平衡。尽可能使PCB上的 热源远离放大器输入电路。强烈建议使用接地层。接地层可降低EMI噪声，还有助于在电路板上保持恒定的 温
度
