High source impedance applications Dual power supply 1.0V to 5.0V The ALD2706A/ALD2706B/ALD2706 is designed to offer a trade-off of Single power supply +2V to +10V performance parameters providing a wide range of desired specifications. High voltage gain Unity gain bandwidth of 0.2MHz It has been developed specifically for the +5V single supply or 1V to 5V Slew rate of 0.1V/s dual supply user and offers the popular industry standard pin configuration. Symmetrical output drive Several important characteristics of the device make application easier to Suitable for rugged, temperature-extreme implement at those voltages. First, each operational amplifier can operate environments with rail to rail input and output voltages. This means the signal input voltage and output voltage can be equal to the positive and negative supply voltages. This feature allows numerous analog serial stages and flexibility APPLICATIONS in input signal bias levels. Second, each device was designed to accommodate mixed applications where digital and analog circuits may Voltage follower/buffer/amplifier operate off the same power supply or battery. Third, the output stage can Charge integrator typically drive up to 25pF capacitive and 20K resistive loads. These Photodiode amplifier features, combined with extremely low input currents, high open loop Data acquisition systems voltage gain of 100V/mV, useful bandwidth of 200KHz, a slew rate of 0.1V/ High performance portable s, low offset voltage and temperature drift, make the ALD2706A/ instruments ALD2706B/ALD2706 a versatile, micropower dual operational amplifier. Signal conditioning circuits A typical ALD2706A/ALD2706B/ALD2706 has the capacity to process a Sensor and transducer amplifiers 0.998V amplitude analog signal with only 1.000V single supply voltage, Low leakage amplifiers while requiring only 0.1pA input bias current. Additionally, robust design Active filters and rigorous screening make this device especially suitable for operation Sample/Hold amplifier in temperature-extreme environments and rugged conditions.
