Using single-ended accelerometers with the 2777A differential charge amplifier
We are replacing our differential accelerometers with 7703A's that have single
ave a 2777A, but cannot find the mounting information.
The 2777A is a low noise, ruggedized remote charge converter for use with differential piezoelectric transducers. This device converts the transducer's high impedance charge input to a low impedance voltage output. The unit should be
C and 2777A have a DCV (direct current voltage) bias established at or near the mid point of the compliance supply voltage as shown in Figure 1. The DCV bias is common to most output stages of single ended devices allowing a dynamic AC signal to swing above and below the DCV bias operating point. Of
