Outputs are stable with virtually any capacitive load. Supply current is less than 750 μA per amplifier in active mode. The AD8591, AD8592, and AD8594 are specified over the Applications for these amplifiers include audio amplification for industrial temperature range (−40°C to +85°C). The AD8591, portable computers, portable phone headsets, sound ports, sound single, is available in the tiny 6-lead SOT-23 package. The AD8592, cards, and set-top boxes. The AD859x family is capable of driving dual, is available in the 10-lead surface-mount MSOP package. The heavy capacitive loads, such as LCD panel reference levels. AD8594, quad, is available in 16-lead narrow SOIC and 16-lead TSSOP packages. The ability to swing rail to rail at both the input and output enables designers to buffer CMOS DACs, ASICs, and other wide output swing devices in single-supply systems.
