General-Purpose CMOS Rail-to-Rail Amplifiers PIN CONFIGURATIONS FEATURES Single-Supply Operation: 2.7 V to 5.5 V Low Supply Current: 45 A/Amplifier Wide Bandwidth: 1 MHz No Phase Reversal Low Input Currents: 4 pA Unity Gain Stable Rail-to-Rail Input and Output APPLICATIONS ASIC Input or Output Amplifier Sensor Interface Piezo Electric Transducer Amplifier Medical Instrumentation Mobile Communication Audio Output Portable Systems GENERAL DESCRIPTION The AD8541/AD8542/AD8544 are single, dual, and quad rail- to-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 a low current consumption of 45 mA 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. Sup- ply current is only 45 mA 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 temperature range (–40 ∞C to +125∞C). The AD8541 is available in 8-lead SOIC, 5-lead SC70, and 5-lead 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 in tape and reel only. 5-Lead SC70 and SOT-23 (KS and RT Suffixes) 1 2 3 5 4 IN A +IN A V+ OUT A AD8541 V 8-Lead SOIC (R Suffix) NC –IN A +IN A V– V+ OUT A NC NC 1 2 3 4 8 7 6 5 AD8541 NC = NO CONNECT 8-Lead SOIC, MSOP, and TSSOP (R, RM, and RU Suffixes) AD8542 1 2 3 4 8 7 6 5 OUT A –IN A +IN A V– +IN B –IN B OUT B V+ 14-Lead SOIC and TSSOP (R and RU Suffixes) AD8544 1 2 3 4 14 13 12 11 OUT A –IN A +IN A V+ V– +IN D –IN D OUT D 5 6 7 10 9 8 +IN B –IN B OUT B OUT C –IN C +IN C |
