It also offers ultralow offset, drift, and voltage noise combined with very low input bias current over the full operating temperature range. With typical offset voltage of only 10 μV, offset drift of 0.5 μV/°C, and noise of only 0.2 μV p-p (0.1 Hz to 10 Hz), it is perfectly suited for applications where large error sources cannot be tolerated. Many systems can take advantage of the low noise, dc precision, and rail-to-rail output swing provided by the AD8622 to maximize the signal-to-noise ratio and dynamic range for low power operation. The AD8622 is specified for the extended industrial temperature range of −40°C to +125°C and is available in lead-free SOIC and MSOP packages. Table 1.
