The is a CMOS Quad Rail-to-rail Input/Output Amplifier features single supply, very low supply current and 1MHz bandwidth. This general purpose amplifier is guaranteed to operate from a 2.7V single supply as well as a 5V supply. These parts provide 1MHz bandwidth at a low current consumption of 45µA per amplifier. The very low input bias currents enable the AD8544 to be used for integrators, photodiode amplifiers, piezoelectric sensors and other applications with high source impedance. The supply current is only 45µA per amplifier, ideal for battery operation. Rail-to-rail inputs and outputs are useful to designers buffering ASICs in single-supply systems. It is optimized to maintain high gains at lower supply voltages, making them useful for active filters and gain stages. The AD8544 is ideal to use in ASIC input or output amplifiers and sensor interfaces as well as piezoelectric transducer amplifiers.
