AD8552ARZ-MS

The AD8552ARZ-MS/AD8554ARZ-MS series represents a new generation of low-noise op-amps, delivering excellent DC accuracy and AC performance. Rail-to-rail input and output, low offset (2μV), low noise (6nV/√Hz), 600μA quiescent current, and 6MHz bandwidth make these devices ideal for a wide range of precision and portable applications. In addition, the wide supply range (2V to 5.5V) combined with excellent power supply rejection makes them well suited for battery-powered applications without regulation. The AD8552ARZ-MS (dual op-amp) and AD8554ARZ-MS (quad op-amp) operate over a temperature range of -25°C to +125°C. The AD8552ARZ-MS/AD8554ARZ-MS are low-noise, unity-gain stable, rail-to-rail precision op-amps operating from a single supply voltage of 2V to 5.5V (±1V to ±2.75V). Supply voltages exceeding 6V (absolute maximum) may permanently damage the amplifier. Rail-to-rail input and output swing significantly extends the dynamic range, particularly in low-supply applications. Good layout practice requires a 0.1μF bypass capacitor placed as close as possible to the supply pins. The AD8552ARZ-MS/AD8554ARZ-MS feature internal phase reversal protection. Many op-amps exhibit phase reversal when the input exceeds the linear common-mode range. This condition is most common in noninverting configurations, where an input beyond the specified common-mode voltage range causes the output to invert to the opposite rail. The inputs of the AD8552ARZ-MS/AD8554ARZ-MS are protected against phase reversal due to common-mode overvoltage; instead, the appropriate rail clamps the output voltage.
