Linear Technology Corporation 1630 McCarthy Blvd., Milpitas, CA 95035-7417 (408)432-1900● FAX:(408)434-0507 ● www.linear-tech.com TYPICAL APPLICATIO This 2-wire remote Geophone preamp operates on a current-loop principle and so has good noise immunity. Quiescent current is ≈10mA for a VOUT of 2.5V. Excitation will cause AC currents about this point of ~ ±4mA for a VOUT of ~±1V max. The op amp is configured for a voltage gain of ~107. Components R5 and Q1 convert the voltage into a current for transmission back to R10, which con- verts it into a voltage again. The LM334 and 2N3904 are not temperature compensated so the DC output contains temperature information.
