... Interface for Pressure Transducers, Position Indicators, Strain Gages, and Other Low Level Signal Sources GENERAL DESCRIPTION The AD22050 is a single-supply difference amplifier for ampli- fying and low-pass filtering small differential voltages (typically 100 gain of 40) from sources having a large common- mode voltage ...

... All min and max specifications are guaranteed, although only those marked in boldface are tested on all production units at final test. Specifications subject to change without notice. Model Temperature Range AD22050N – +125 C AD22050R – +125 C AD22050R-Reel – +125 C *Quantities must be in increments of 2,500 pieces each + and ...

... ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the AD22050 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality ...

... V – 0.2 V) with large differential input voltages. The input of S the AD22050 is limited to no greater than (V – 0.2)/10, for overall gains less than 10, since the preamplifier, with its fixed gain of 10, reaches its full scale output before the output buffer. For this is 0 ...

... If the maximum battery voltage spikes up to +20 V, the common mode voltage at the input can be as high as 21.5 V. This can be measured using even supply for the AD22050. –5– AD22050 has the same 3 has at a frequency (see the graph in ...

... V. By adding an additional load, as shown, the output swing toward ground can be extended. The relationship is described by: ANALOG COMMON *This 20 k resistor is internal to the AD22050 and can vary by 30%. where R L cannot be made arbitrarily small since this would require exces- sive current from the output ...

... R Since the perturbations from the analog-to-digital converter are small, the output of the AD22050 will appear low impedance. The transient response will, therefore, have a time constant governed by the product of the two lag compo- ...
