**OP293ESZ-REEL7: A Comprehensive Technical Overview of the Precision Dual Op-Amp**

The **OP293ESZ-REEL7** represents a high-performance, precision dual operational amplifier from Analog Devices, engineered to deliver exceptional accuracy and reliability in a compact package. This device, supplied in a **8-lead SOIC package** and on a 7-inch reel, is optimized for applications where low power consumption, high precision, and robust performance are paramount.

At the core of the OP293's design is its **ultra-low input offset voltage**, typically 150 µV, which is crucial for minimizing errors in precision DC amplification and measurement circuits. This is complemented by an exceptionally **low input offset voltage drift** of just 1.5 µV/°C, ensuring stable performance across a wide temperature range. The amplifier operates on a **single-supply voltage from 3 V to 36 V** or dual supplies of ±1.5 V to ±18 V, offering remarkable flexibility for both portable and industrial equipment. A key feature is its **low supply current of 45 µA per amplifier**, making it an ideal choice for battery-powered and energy-sensitive systems.

The OP293 excels in applications requiring high impedance sensing and accurate signal conditioning. Its **high open-loop gain of 600 V/mV** and **common-mode rejection ratio (CMRR) of 120 dB** ensure that signals are amplified with high fidelity, rejecting noise and common-mode interference effectively. Furthermore, the device incorporates internal frequency compensation, providing stable operation without requiring external components.

Typical applications span a diverse set of fields, including:

* **Precision Sensor Signal Conditioning** (thermocouples, strain gauges, bridge amplifiers)

* **Portable and Battery-Powered Medical Instrumentation**

* **High-Impedance Current Sensing**

* **Active Filters and Precision Integrators**

* **4-20 mA Current-Loop Transmitters**

**ICGOOODFIND**: The OP293ESZ-REEL7 stands out as a superior solution for designers seeking a balance of precision, low power, and versatility. Its exceptional electrical characteristics, robust performance over temperature, and single-supply capability make it an indispensable component in modern analog design, particularly where accuracy cannot be compromised.
