The products have true single supply capability with rail-to-rail input and output characteristics and are specified for +2.7 V, +5 V and 5 V supplies. The input voltage range can extend to 500 mV beyond each rail. The output voltage swings to within 20 mV of each rail providing the maximum output dynamic range. The AD8031/AD8032 also offer excellent signal quality for only 800 A of supply current per amplifier; THD is 62 dBc with a 2 V p-p, 1 MHz output signal and 86 dBc for a 100 kHz, 4.6 V p-p signal on +5 V supply. The low distortion and fast settling time make them ideal as buffers to single supply, A-to-D converters.
