The AD8541/AD8542/AD8544 are single, dual and quad railto- rail input and output single supply amplifiers featuring very low supply current and 1 MHz bandwidth. All are guaranteed to operate from a +2.7 V single supply as well as a +5 V supply. These parts provide 1 MHz bandwidth at low current consumption of 45 A per amplifier. Very low input bias currents enable the AD8541/AD8542/AD8544 to be used for integrators, photodiode amplifiers, piezo electric sensors and other applications with high source impedance. Supply current is only 45 A per amplifier, ideal for battery operation. Rail-to-rail inputs and outputs are useful to designers buffering ASICs in single supply systems. The AD8541/AD8542/AD8544 are optimized to maintain high gains at lower supply voltages, making them useful for active filters and gain stages.
The AD8541/AD8542/AD8544 are specified over the extended industrial (40°C to +125°C) temperature range. The AD8541 is available in 8-lead SO and 5-lead SOT-23 packages. The AD8542 is available in 8-lead SO, 8-lead MSOP, and 8-lead TSSOP surface mount packages. The AD8544 is available in 14-lead narrow SO-14 and 14-lead TSSOP surface mount packages.
All TSSOP, MSOP, and SOT versions are available in tape and reel only.
