Description

The CS5540 is a low-power and low-voltage ?Σ analog-to-digital converter (ADC), which achieves highly accurate conversions using a simple non-programmable interface that is easy to understand and design-in. It is optimized to convert analog signals in DC measurement applications, such as temperature and pressure measurement, and various portable devices where low-power consumption is required.
