Additional Details:
The OPA4347EA is a quad op-amp available in an SOIC-14 package. It is characterized by its low supply current, typically a few microamperes per amplifier. The input voltage range extends beyond the supply rails, allowing for input signals that may exceed the supply voltage. The output swings rail-to-rail, providing the maximum possible output voltage swing. It operates over a temperature range of -40°C to +85°C. The OPA4347 is designed for stability and low distortion, making it suitable for demanding low-power applications. The device is also available in other package options.
