低偏移、零漂移运算放大器提供宽增益带宽，实现高精度传感

The TSZ151 op amps have very low offset voltage with minimal temperature drift, offering high accuracy and stability to circuits for sensor interfacing, signal conditioning, and current measurement.

TSZ151运算放大器具有非常低的偏移电压和最小的温度漂移，为传感器接口、信号调节和电流测量的电路提供了高精度和稳定性。

An extremely low input offset voltage (Vio) is the defining parameter of a high-accuracy operational amplifier (op amp). The TSZ151 has Vio less than 7 µV at 25°C. Moreover, the value remains stable, below 10 µV, over the full specified temperature range, from -40 to 125 °C. Its high stability minimizes reliance on periodic recalibration, enhancing availability of the end product throughout its lifetime.

极低的输入偏移电压 (Vio) 是高精度运算放大器 (op amp) 的定义参数。TSZ151在25°C下的Vio小于7µV。此外，在-40至125°C的整个指定温度范围内，该值可稳定低于10µV。这样的高稳定性显著减少了对定期重新校准的依赖，提高了成品在整个生命周期内的可用性。

With gain-bandwidth of 1.6 MHz and drawing just 210 μA at 5 V, the TSZ151 sits between ST’s 400 kHz TSZ121 and 3MHz TSZ181, giving designers more choice and flexibility to optimize speed and power consumption. The TSZ151 combines its excellent speed-to-power ratio with ultra-low maximum input bias current of 300 pA.

TSZ151的增益带宽为1.6 MHz，在5 V下仅消耗210μA，介于意法半导体的400 kHz TSZ121和3MHz TSZ181之间。这为设计者提供了更多选择和灵活性，以优化速度和功耗。TSZ151同时兼具出色的速度功率比，以及300 pA的超低最大输入偏置电流。

Having a minimum operating voltage of 1.8 V, the TSZ151 can be powered from the same rail as other ICs in the system, such as a low-voltage microcontroller. The rail-to-rail input and output help maximize dynamic range. The op amp also has very low power consumption, drawing just 210 μA at 5 V, while the low supply-voltage capability permits extended runtime with a discharged battery.

TSZ151的最低工作电压为1.8V，可与系统中的其他IC（如低压微控制器）共享电源。轨对轨输入/输出有助于动态范围的充分扩大。除此之外，运算放大器的功耗也非常低，在5V时仅消耗210μA，而低电源电压能力允许其在电池放电的情况下延长运行时间。

Leveraging its wide operating temperature range, from -40 to +125°C, designers can use the TSZ151 in equipment to be deployed in harsh environments and in applications with long mission profiles. Typical uses include feedback circuitry in power supplies for industrial, server and telecom-infrastructure applications, and automotive high-accuracy signal conditioning and power conversion. The TSZ151 is AEC-Q100 qualified and is covered by ST’s rolling 10-year longevity plan that guarantees long-term product support.

得益于-40至+125°C的宽工作温度范围，设计者可在恶劣环境和长任务概述应用中部署的设备中使用TSZ151。其典型的用途包括工业、服务器和电信基础设施应用电源中的反馈电路，以及汽车高精度信号调节和电源转换。TSZ151符合AEC-Q100标准，并已纳入意法半导体的10年长期供货计划，以保证长期的产品支持。

Currently in mass production, the TSZ151 is offered in compact SC70-5 and SOT23-5 packages.
