Description
The RRA78620 is a dual operational amplifier (op amp) featuring low power consumption and rail-to-rail input and output capabilities. It operates on supply voltages ranging from 1.8V to 5.5V, making it suitable for a wide range of general-purpose applications. The device is unity-gain stable, ensuring reliable performance across various use cases.
The input common-mode voltage range extends 100mV above and below the power supply voltage rails, enabling compatibility with virtually any single-supply application. The rail-to-rail input and output swing enhances signal dynamic range and signal-to-noise ratio, a critical advantage in low-supply applications. With high signal bandwidth and a high slew rate, the RRA78620 is ideal for driving the sample-and-hold circuitry of analog-to-digital converters (ADCs). Additionally, the output stage can swing to within 20mV of the supply rails with a 10kΩ load, ensuring efficient and precise operation.
