TLV9041 Ultra Low Voltage Op Amp IC

The low-powerTLV9041includes a single ultra-low-voltage (1.2 V to 5.5 V) operational amplifier (op-amps) with rail-to-rail input and output swing capabilities. The TLV9041 enables power savings both with its low quiescent current (10 µA, typ.) and the ability to operate at supply voltages as low as 1.2 V, making it one of the few amplifiers in the industry capable of 1.5-V coin cell applications.

Where to use TLV9041

The TLV9041 is aSingle Package Operational Amplifier，，，，meaning it has a single Op-Amps inside it and can be used in many different applications.

TLV9041运算放大器的主要区别特征是它们是针对音频应用完全指定的超低失真，低噪声操作放大器。需要具有成本效益的解决方案，用于烟雾探测器，可穿戴电子设备和小型电器，其中需要低压操作和高电容式驱动器。TLV9041的电容载荷驱动器为500 pf，电阻开路输出阻抗使稳定化更加容易，而电容载荷更高。这些操作放大器专门针对低压操作（1.2 V至5.5 V）设计，其性能规格与TLV600X设备相似，并且能够在供应电压低至1.2 V的能力下进行操作，使其成为少数几个放大器之一该行业能够具有1.5-V硬币细胞应用。可以使用关闭模式可以实现进一步的功率，该模式可以关闭放大器并进入备用模式，而典型的电流消耗小于150 Na。这些设备为电源和空间受限的应用提供了具有成本效益的放大器解决方案，例如电池供电的物联网设备，可穿戴电子设备以及低压操作至关重要的个人电子设备。

The device also delivers excellent AC performance with a gain bandwidth of 350 kHz and a high cap load drive of 100 pF, enabling designers to achieve both improved performance and lower power consumption

Space-saving micro-size packages, such as X2QFN and WSON, are offered for all channel variants (single, dual, and quad), along with industry-standard packages such as SOIC, VSSOP, TSSOP, and SOT-23 packages.

Special Features ofTLV9041我知道了

TLV9041是低功耗,轨到轨input, and output op-amps. These devices operate from 1.2 V to 5.5 V, and are unity-gain stable, and are designed for a wide range of general-purpose applications. The input common-mode voltage range includes both rails and allows the TLV9041 devices to be used in any single-supply application. Rail-to-rail input and output swing significantly increases dynamic range, especially in low-supply applications, and makes them suitable for driving sampling analog-to-digital converters (ADCs). Other than that, this IC has many different some of which are discussed below。

TLV9041 IC可以从1.2 V到5.5V。此外，许多规格从–40°C到125°C。TLV9041 IC的输入共同模式电压范围延伸至任何一个供应轨。即使在1.2 V的超低电源电压下运行，直到标准电源电压为5.5 V，这也是正确的，这意味着它是轨道轨道运输工具的。

TLV9041设计用于需要驱动电容载荷的应用。与所有操作放大器一样，在某些特定情况下，TLV9041可能变得不稳定。特定的操作放大器电路配置，布局，增益和输出加载是确定放大器是否稳定运行时要考虑的一些因素。

过载恢复定义为操作放大器输出所需的时间，以从饱和状态恢复到线性状态。当输出电压超过额定工作电压时，操作放大器的输出设备由于高输入电压或高增益而进入饱和区域。一旦输出设备之一进入饱和区域，输出阶段就需要额外的时间返回线性操作状态，该状态称为过载恢复时间。

TLV9041使用集成的电磁干扰（EMI）过滤来减少来自无线通信和诸如密集填充的板的效果，并混合了模拟信号链和数字组件。通过电路设计技术可以改善EMI免疫力；TLV9041受益于这些设计改进。
