Cirrus Logic has introduced the Single-S seismic platform, which combines a modulator and digital filter to create a high-resolution single-sensor measurement system for seismic and geophysical data acquisition. The system requires low power consumption and has a very small footprint, enabling end-measurement instruments to perform efficiently and accurately in a smaller, lighter package.
The CS5378 is a multifunction digital filter using a low-power signal processing architecture to achieve efficient filtering for Delta-Sigma modulators. Digital filter coefficients are included on chip or can be programmed for custom applications. It provides highly integrated peripherals for simplified system design, including selectable digital filter decimation ratios, offset and gain connections, a digital test bit-stream signal generator, time break control and eight general purpose input/output pins.
The CS5373A is a single-channel, high-performance, low-power, fourth-order Delta-Sigma modulator that uses a low-power signal processing architecture to achieve efficient filtering. The two systems combined produce a compact self-testing, analog-to-digital measurement system ideal for single-sensor seismic and geophysical applications.
