Advanced Linear Devices ALD2711BPAL

The ALD2711A/ALD2711B/ALD2711 is a dual monolithic CMOS micropower precision high slew rate 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. Typical supply current is 200μA at 5V supply voltage. It is manufactured with Advanced Linear Devices' enhanced ACMOS silicon gate CMOS process. The ALD2711A/ALD2711B/ALD2711 has been developed specifically for the +5V single supply or ±1V to ±5V dual supply user and has an input stage that operates to +300mV above and -300mV below the supply voltages with no adverse effects and/or phase reversals. Several important characteristics of the device make application easier to implement at those voltages. First, each operational amplifier can operate with rail to rail input and output voltages. This means the signal input voltage and output voltage can be at the positive and negative supply voltages. This feature allows numerous analog serial stages and flexibility in input signal bias levels. Second, each 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, high useful bandwidth, and slew rate make the ALD2711A/ALD2711B/ALD2711 a versatile, micropower operational amplifier. The ALD2711A/ALD2711B/ALD2711 with on-chip offset voltage trimming allows the device to be used without nulling in most applications. Additionally, robust design and rigorous screening make this device especially suitable for operation in temperature-extreme environments and rugged conditions. The unique characteristics of the ALD2711A/ALD2711B/ALD2711 are modeled in an available macromodel.
