These amplifiers have very low input bias currents, making them suitable for integrators and diode amplification. Outputs are stable with virtually any capacitive load. Supply current is less than 750 μA per amplifier in active mode.
Applications for these amplifiers include audio amplification for portable computers, portable phone headsets, sound ports, sound cards, and set-top boxes. The AD859x family is capable of driving heavy capacitive loads, such as LCD panel reference levels.
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.
The AD8591, AD8592, and AD8594 are specified over the industrial temperature range (−40°C to +85°C). The AD8591, single, is available in the tiny 6-lead SOT-23 package. The AD8592, dual, is available in the 10-lead surface-mount MSOP package. The AD8594, quad, is available in 16-lead narrow SOIC and 16-lead TSSOP packages.
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
- EVAL-PRAOPAMP-2CPZ (dual 8-lead LFCSP) CP-8
- EVAL-PRAOPAMP-2RMZ (dual 8-lead MSOP) RM-8
- EVAL-PRAOPAMP-2RZ (dual 8-lead SOIC) R-8
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well.
