9.1 Application Information

The ADS1287 is a high-resolution ADC optimized for low-power operation in seismic data acquisition equipment. Optimum performance requires special attention to the support circuitry and printed-circuit board (PCB) layout. As much as possible, locate noisy digital components (such as microcontrollers, oscillators, and so forth) in a PCB area away from the ADC and analog front-end components. Locating the digital components close to the power-entry point keeps the digital current return path short and separated from sensitive analog components.
