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 (–...
