... The ALD1722E/ALD1722 is a monolithic rail-to-rail precision CMOS operational amplifier with integrated user programmable EPAD (Electri- cally Programmable Analog Device) based offset voltage adjustment. The ALD1722E/ALD1722 is a direct replacement of the ALD1702 operational amplifier, with the added feature of user-programmable offset voltage trimming resulting in significantly enhanced total system performance and user flexibility ...

... In this case, the circuit design must provide for the ALD1722E to operate in normal mode and in programming mode. One of the benefits of in-system programming is that not only is the ALD1722E offset voltage from operating bias conditions accounted for, any residual errors introduced by other circuit components, such as resistor or sensor induced voltage errors, can also be cor- rected. In this way, the “ ...

... In addition, optional decoupling capacitors of 1000pF or greater value can be added to VE1 and VE2 terminals. F. The ALD1722E/ALD1722 is designed for use in low voltage, micro-power circuits. The maximum operating voltage during normal operation should remain below 10 Volts at all times. Care ...
