Amplifier, buffer instrumentation

Short connections - generally the control instrument e.g. fX)tentiostat should be located near the cell to ensure short electrical connections. If this is not feasible the use of a buffer amplifier in the control loop near the test cell is to be considered. [Pg.21]

FIGURE 10.287 An active-balanced input circuit using three op-amps to form an instrumentation-grade circuit. The input signals are buffered, then applied to a differential amplifier. [Pg.1243]

Galvanostat, Fig. 3 Instrumentation consisting of a differential amplifier and two buffers to minimize input currents... [Pg.926]

The signal is buffered by a more complex differential amplifier [14] (preferentially an instrumentation amplifier, DA in Fig. 2). The cell current I is given by... [Pg.1700]

Buffer amplifiers were also needed between a few sisals In the Instrumentation and the data acqulsi-tloa cards. No specific design is given in this report many desigas based on operational amplifiers would have worked, since there was no exceptional requirement... [Pg.104]
