GENERAL DESCRIPTION
All device characteristics are specified for +5V single supply or ±2.5V dual supply systems. Supply current is 40µA maximum at 5V supply voltage. Several important characteristics of the device make application easier to implement at those voltages. First, the operational amplifier can operate with rail to rail input and output voltages. This means the signal input voltage and output voltage can be close to or equal to the positive and negative supply voltages. This feature allows numerous analog serial stages and flexibility in input signal bias levels. Second, the device was designed to accommodate mixed applications where digital and analog circuits may operate off the same power supply or battery. Third, the output stage can typically drive up to 25pF capacitive and 20KΩ resistive loads. These features, combined with extremely low input currents, high open loop voltage gain of 100V/mV, useful bandwidth of 400KHz, a slew rate of 0.17V/µs, low offset voltage and temperature drift, make the ALD1726/ALD1726G a versatile, micropower operational amplifier.
