APPLICATIONS  
GENERAL DESCRIPTION  
• Sensor interface circuits  
The ALD1721E/ALD1721 is a monolithic rail-to-rail precision CMOS  
operational amplifier with integrated user programmable EPAD (Electri-  
callyProgrammableAnalogDevice)basedoffsetvoltageadjustment. The  
ALD1721E/ALD1721 operational amplifier is a direct replacement of the  
ALD1701 operational amplifier, with the added feature of user-program-  
mable 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 preci-  
sion 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 programmed, the set parameters are stored indefinitely  
within the device even after power-down. EPAD offers the circuit designer  
a convenient and cost-effective trimming solution for achieving the very  
highest amplifier/system performance.  
• Transducer biasing circuits  
• Capacitive and charge integration circuits  
• Biochemical probe interface  
• Signal conditioning  
• Portable instruments  
• High source impedance electrode  
amplifiers  
• 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 ALD1721E/ALD1721 operational amplifier features rail-to-rail input  
and output voltage ranges, tolerance to over-voltage input spikes of  
300mV beyond supply rails, capacitive loading up to 50pF, extremely low  
input currents of 0.01pA typical, high open loop voltage gain, useful  
bandwidth of 700KHz, slew rate of 0.7 V/µs, and low typical supply current  
of 120 uA.
