**The OP293FSZ-REEL7: A Precision Dual Op-Amp for Low-Voltage, Single-Supply Applications**
The operational amplifier remains a cornerstone of analog circuit design, and the quest for devices that combine precision, low power consumption, and single-supply operation is ongoing. The **OP293FSZ-REEL7** stands out as a premier solution specifically engineered to excel in these demanding areas. This precision dual operational amplifier integrates two high-performance op-amps in a single package, offering designers a compact and reliable component for a wide array of modern electronic applications.
A defining characteristic of the OP293FSZ-REEL7 is its **optimization for single-supply operation from +3 V to +36 V**. This wide range, which also includes dual-supply operation from ±1.5 V to ±18 V, provides exceptional flexibility. It allows the device to be powered directly from standard lithium-cell batteries, 3.3 V or 5 V logic supplies, or higher industrial rails, making it a versatile choice for portable, battery-powered, and industrial equipment alike.
Precision is paramount in applications such as sensor interfacing, instrumentation, and data acquisition. The OP293FSZ-REEL7 delivers on this front with outstanding electrical specifications. It features a **very low input offset voltage of 150 μV maximum**, which minimizes errors in DC signal amplification. Coupled with a **remarkably low supply current of 45 μA per amplifier**, it achieves an excellent balance between accuracy and power efficiency. This low quiescent current is crucial for extending battery life in portable devices without compromising signal integrity.
Furthermore, the amplifier exhibits a high open-loop gain of 600 V/mV, ensuring high gain accuracy in closed-loop configurations. Its common-mode input range extends below the negative rail, which is a critical feature for single-supply systems where signals often need to be amplified near ground. The output stage is also designed to swing rail-to-rail, maximizing the dynamic range available to the designer, especially when operating at lower supply voltages.
**Typical applications** for the OP293FSZ-REEL7 are diverse and include:
* Portable and battery-powered medical instrumentation
* Precision filter circuits
* Thermocouple and thermopile amplifier circuits
* Handheld test equipment
* Active filters and transducer amplifiers
Housed in an industry-standard 8-lead SOIC package, the OP293FSZ-REEL7 is suitable for automated PCB assembly, streamlining the manufacturing process. Its combination of precision, low-voltage operation, and minimal power draw makes it an indispensable component for designers tackling the challenges of today's analog systems.
**ICGOOFind:** The OP293FSZ-REEL7 is a high-precision, low-power dual operational amplifier that masterfully combines accuracy with energy efficiency. Its ability to operate seamlessly on a single supply voltage, **rail-to-rail output swing**, and **ultra-low supply current** make it an ideal choice for designers working on space-constrained, battery-sensitive applications where every millivolt and microamp counts.
