OP193/OP293 INPUT OVERVOLTAGE PROTECTION As previously mentioned, the OP193/OP293 op amps use a PNP input stage with protection resistors in series with the inverting and noninverting inputs. The high breakdown of the PNP transistors, coupled with the protection resistors, provides ...

A MICROPOWER FALSE-GROUND GENERATOR Some single-supply circuits work best when inputs are biased above ground, typically at ½ of the supply voltage. In these cases, a false ground can be created by using a voltage divider buffered by an amplifier. ...

OP193/OP293 A SINGLE-SUPPLY INSTRUMENTATION AMPLIFIER Designing a true single-supply instrumentation amplifier with zero-input and zero-output operation requires special care. The traditional configuration, shown in Figure 33, depends upon Amplifier A1’s output being when the applied common- mode ...

From the formulas, it can be seen that if the span trim is adjusted before the zero trim, the two trims are not interactive, which greatly simplifies the calibration procedure. Calibration of the transmitter is simple. First, the slope of ...
