GENERAL DESCRIPTION The ALD2731A/ALD2731 is a precision dual low-cost high-slew-rate monolithic CMOS micropower operational amplifier intended for a broad range of analog applications using ±1V to ±5V dual power supply systems, as well as +2V to +10V battery operated systems. All device characteristics are specified for +5V single supply or ±2.5V dual supply systems. Supply current is 250µA per amplifier maximum at 5V supply voltage. It is manufactured with Advanced Linear Devices' enhanced EPAD® silicon gate CMOS process. The ALD2731A/ALD2731 features extremely low input power require- ments, practically removing any leading effects on high source imped- ance signal sources such as cpacitive sensors. These devices do not add any significant errors, regardless of what the souce impedance variations may be, thereby improving overall system precision and accuracy. The device is designed to offer the benefits of CMOS technology by providing a wide range of desired specifications. The most important of these specifications is extremely low input bias/offset currents at extremely low input offset voltages. It has been developed specifically for the +5V single supply or ±1V to ±5V dual supply user and offers the popular industry standard pin configuration of µA741 and ICL7611 types. Several additional important characteristics of the device make applica- tion 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 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 50pF capacitive and 10KΩ resistive loads. These features, combined with extremely low input currents, high open loop voltage gain of 100V/mV, useful bandwidth of 700KHz, a slew rate of 0.7V/µs, low power dissipation of 0.5mW, low offset voltage and temperature drift, make the ALD2731A/ALD2731 a versatile, micropower operational amplifier. The ALD2731A/ALD2731, designed and fabricated with silicon gate CMOS technology, offers 0.01pA typical input bias current. On chip offset voltage trimming, using EPAD technology, allows the device to be used without nulling. Additionally, robust design and rigorous screening make this device especially suitable for operation in temperature-extreme environments and rugged conditions.
