低偏移、零漂移運(yùn)算放大器提供寬增益帶寬，實(shí)現(xiàn)高精度傳感

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運(yùn)算放大器具有非常低的偏移電壓和最小的溫度漂移，為傳感器接口、信號(hào)調(diào)節(jié)和電流測(cè)量的電路提供了高精度和穩(wěn)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.

極低的輸入偏移電壓 (Vio) 是高精度運(yùn)算放大器 (op amp) 的定義參數(shù)。TSZ151在25°C下的Vio小于7μV。此外，在-40至125°C的整個(gè)指定溫度范圍內(nèi)，該值可穩(wěn)定低于10μV。這樣的高穩(wěn)定性顯著減少了對(duì)定期重新校準(zhǔn)的依賴(lài)，提高了成品在整個(gè)生命周期內(nèi)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的增益帶寬為1.6 MHz，在5 V下僅消耗210μA，介于意法半導(dǎo)體的400 kHz TSZ121和3MHz TSZ181之間。這為設(shè)計(jì)者提供了更多選擇和靈活性，以?xún)?yōu)化速度和功耗。TSZ151同時(shí)兼具出色的速度功率比，以及300 pA的超低最大輸入偏置電流。

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的最低工作電壓為1.8V，可與系統(tǒng)中的其他IC（如低壓微控制器）共享電源。軌對(duì)軌輸入/輸出有助于動(dòng)態(tài)范圍的充分?jǐn)U大。除此之外，運(yùn)算放大器的功耗也非常低，在5V時(shí)僅消耗210μA，而低電源電壓能力允許其在電池放電的情況下延長(zhǎng)運(yùn)行時(shí)間。

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的寬工作溫度范圍，設(shè)計(jì)者可在惡劣環(huán)境和長(zhǎng)任務(wù)概述應(yīng)用中部署的設(shè)備中使用TSZ151。其典型的用途包括工業(yè)、服務(wù)器和電信基礎(chǔ)設(shè)施應(yīng)用電源中的反饋電路，以及汽車(chē)高精度信號(hào)調(diào)節(jié)和電源轉(zhuǎn)換。TSZ151符合AEC-Q100標(biāo)準(zhǔn)，并已納入意法半導(dǎo)體的10年長(zhǎng)期供貨計(jì)劃，以保證長(zhǎng)期的產(chǎn)品支持。

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