All device characteristics are specified for +5V single supply Rail to rail input and output voltage ranges or 2.5V dual supply systems. Supply current is 40A maximum at 5V No frequency compensation required -- unity supply voltage. gain stable Extremely low input bias currents -- 0.1pA The ALD1726/ALD1726G is designed to offer high performance for a typical (30pA max.) wide range of applications requiring very low power dissipation. It has Ideal for high source impedance applications been developed specifically for the +5V single battery or 1V to 5V dual Dual power supply 1.0V to 5.0V operation battery user and offers the popular industry standard single operational Single power supply +2V to +10V operation amplifier pin configuration. High voltage gain -- typically 100V/mV 2.5V (100dB) Several important characteristics of the device make application easier Drive as low as a 20K load to implement at those voltages. First, the operational amplifier can Output short circuit protected operate with rail to rail input and output voltages. This means the signal Unity gain bandwidth of 0.4MHz input voltage and output voltage can be close to or equal to the positive Slew rate of 0.17V/s and negative supply voltages. This feature allows numerous analog Suitable for rugged, temperature-extreme serial stages and flexibility in input signal bias levels. Second, the environments 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 APPLICATIONS 20K resistive loads. These features, combined with extremely low input currents, high open loop voltage gain of 100V/mV, useful band- Voltage amplifier width of 400KHz, a slew rate of 0.17V/s, low offset voltage and Voltage follower/buffer temperature drift, make the ALD1726/ALD1726G a versatile, Charge integrator micropower operational amplifier.
