SINGLE-CHANNEL SEISMIC SYSTEM

Figure 51 illustrates a single-channel data acquisition concept for seismic. The DAC1282 is used to test both the

ADC and geophone. The DAC1282 connects directly to channel 1 of the ADC. Tests of the ADC include THD,

pulse, input noise, common-mode, etc. The DAC output and ADC sample timing are controlled by the SYNC

input pins.

The geophone connects to channel 2 of the ADC through input protection and optional filter networks. The DAC

connects to the geophone using the integrated signal switch. Series resistors isolate the geophone from the DAC

output. Geophone test capabilities include impulse, THD, leakage, and common-mode.
