AD8541/AD8542/AD8544

Universal CMOS Rail-to-Rail Amplifier

The AD8541/AD8542/AD8544 are single, dual, and quad rail-to-rail input and output single-supply amplifiers with very low supply current and 1 MHz bandwidth. All are guaranteed to operate from a single 2.7 V supply and a 5 V supply.

These parts provide 1 MHz bandwidth at a low current consumption of 45 mA per amplifier. The very low input bias current allows the AD8541/AD8542/ad8544 to be used in integrators, photodiode amplifiers, piezoelectric sensors, and other high source impedance applications. Standby current is only 45mA per amplifier, ideal for battery operation. In single-supply systems, rail-to-rail input and output are useful for buffer IC designs. The AD8541/AD8542/ad8544 are optimized to maintain high gain at lower supply voltages, making them suitable for active filters and gain stages. The AD8541/AD8542/AD8544 are specified over the extended industrial temperature range (-40∞C to +125∞C).

The ad8541 is available in 8-on SOIC, 5-on SC70 and 5-on sot-23 packages. The AD8542 is available in 8-lead SOIC, 8-lead msop, and 8-lead TSSOP surface mount packages. The ad8544 is available in 14-lead narrow SOIC and 14-lead TSSOP surface mount packages. All MSOP, SC70 and SOT versions are available on tape and reel only
