Renesas Electronics RRA786x0 CMOS Operational Amplifiers
Renesas Electronics RRA786x0 CMOS Operational Amplifiers (Op Amps) include the RRA78610 (single), RRA78620 (dual), and RRA78640 (quad) devices. The Renesas RRA786x0 op amps feature low power consumption and rail-to-rail input and output capabilities. The op amps operate on supply voltages ranging from 1.8V to 5.5V, making the devices suitable for a wide range of general-purpose applications. The devices are 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. With high signal bandwidth and a high slew rate, the Renesas RRA786x0 family 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.
