The AD8631 brings precision and bandwidth to the SOT-23-5 package at single supply voltages as low as 1.8 V and low supply current. The small package makes it possible to place the AD8631 next to sensors, reducing external noise pickup. The AD8631 and AD8632 are rail-to-rail input and output bipolar amplifiers with a gain bandwidth of 4 MHz and typical voltage offset of 0.8 mV from a 1.8 V supply. The low supply current and the low supply voltage makes these parts ideal for battery-powered applications. The 3 V/µs slew rate makes the AD8631/AD8632 a good match for driving ASIC inputs, such as voice codecs. The AD8631/AD8632 is specified over the extended industrial (40 C to +125 C) temperature range. The AD8631 single is available in 5-lead SOT-23 surface-mount packages. The dual AD8632 is available in 8-lead SOIC and µSOIC packages.

CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the AD8631/AD8632 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.
