AD625 THEORY OF OPERATION The AD625 is a monolithic instrumentation amplifier based on a modification of the classic three-op-amp approach. Monolithic construction and laser-wafer-trimming allow the tight matching and tracking of circuit components. This insures the high level of performance ...

Any resistors in series with the inputs of the AD625 will degrade the noise performance. For this reason the circuit in Figure 26b should be used if the gains are all greater than 5. For gains less than 5, either ...

AD625 the I × R drops “inside the loop” and virtually eliminating this error source. Typically, IC instrumentation amplifiers are rated for a full ± 10 volt output swing into 2 kΩ. In some applications, however, the need exists to ...

Offset voltage and offset voltage drift each have two compo- nents: input and output. Input offset is that component of offset that is generated at the input stage. Measured at the output it is directly proportional to gain, i.e., input ...

AD625 GROUND RETURNS FOR BIAS CURRENTS Input bias currents are those currents necessary to bias the input transistors amplifier. There must be a direct return path for these currents, otherwise they will charge external capaci- tances, causing ...

These capacitances may also be incorporated as part of the external input protection circuit (see section on Input Protec- tion general practice every effort should be made to match the extraneous capacitance at Pins 15 and 2, and ...
