TLV854x超低功率运算放大器

Texas Instruments TLV854x双通道超低功耗运算放大器（运放）旨在用于无线和低功耗有线设备中的成本优化型感测应用。TLV854x可最大限度地降低诸如运行检测安全系统（如微波和PIR运动传感）等运行电池寿命至关重要的设备中的功耗。这些器件还具有精心设计的CMOS输入级，可实现非常低的毫微微安偏置电流，从而降低IBIAS和IOS误差，否则会影响敏感应用。这些应用的示例包括具有兆欧级反馈电阻器的跨阻抗放大器 (TIA) 配置和高源阻抗感测应用。此外，内置的电磁干扰 (EMI) 保护功能可降低器件对手机、WiFi、无线发射器、标签阅读器所发出意外射频信号的灵敏度。

Texas Instruments | Amplifiers & Linear TLV854x Nanopower Operational Amplifiers

Texas Instruments TLV854x Nanopower Operational Amplifiers are intended for cost-optimized sensing applications in wireless and low-power wired equipment. The TLV854x family of op amps minimize power consumption in equipment such as motion detecting security systems (like microwave and PIR motion sensing) where operational battery life is critical. They also have a carefully designed CMOS input stage, enabling very low, femto-ampere bias currents, thereby reducing IBIAS and IOS errors that would otherwise impact sensitive applications. Examples of these applications include transimpedance amplifier (TIA) configurations with megaohm feedback resistors, and high source impedance sensing applications. Additionally, built-in EMI protection reduces sensitivity to unwanted RF signals from sources such as mobile phones, WiFi, radio transmitters and tab readers.
