APPLICATIONS

GENERAL DESCRIPTION

• Sensor interface circuits

The ALD1726E is a monolithic rail-to-rail ultra-micropower precision

CMOS operational amplifier with integrated user programmable EPAD

(Electrically Programmable Analog Device) based offset voltage adjust-

ment. The ALD1726E is a direct replacement of the ALD1706 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

aidofapersonal computerundersoftwarecontrol. Onceprogrammed,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 perfor-

mance.

• 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 ALD1726E operational amplifier features rail-to-rail input and output

voltage ranges, tolerance to over-voltage input spikes of 300mV beyond

supply rails, extremely low input currents of 0.01pA typical, high open loop

voltage gain, useful bandwidth of 200KHz, slew rate of 0.17V/µs, and low

typical supply current of 25µA.
