APPLICATIONS  
GENERAL DESCRIPTION  
The ALD1722E/ALD1722 is a monolithic rail-to-rail precision CMOS  
operational amplifier with integrated user programmable EPAD (Electri-  
callyProgrammableAnalogDevice)basedoffsetvoltageadjustment. 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. EPAD technology is an exclusive ALD design which has  
been refined for analog applications where precision voltage trimming is  
necessary to achieve a desired performance. It utilizes CMOS FETs as  
in-circuit elements for trimming of offset voltage bias characteristics with  
the aid of a personal computer under software control. Once pro-

effective trimming solution for achieving the very highest amplifier/system  
performance.

• Precision Sample and Hold amplifiers  
• Precision current to voltage converter  
• Error correction circuits  
• Sensor compensation circuits  
• Precision gain amplifiers  
• Periodic In-system calibration  
• System output level shifter  
The ALD1722E/ALD1722 operational amplifier features rail-to-rail input  
and output voltage ranges, tolerance to over-voltage input spikes of  
300mV beyond supply rails, high capacitive loading up to 4000pF, ex-  
tremely low input currents of 0.01pA typical, high open loop voltage gain,  
useful bandwidth of 1.5 MHz, slew rate of 2.1 V/µs, and low supply current  
of 0.8mA.
