CS5540

The CS5540 is a low-power and low-voltage analog- to-digital converter (ADC), which achieves highly accurate conversions using a simple non-programmable interface that is easy to understand and design-in. CS5540 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.

To accommodate these applications, CS5540 ADC integrates analog input and reference buffers for increased input impedance and a two-channel multiplexer.

The CS5540 includes a digital filter, which achieves simultaneous rejection of 50/60 Hz signals and provides single conversion settling at 6.7 SPS throughput. Absolute accuracy is achieved via continuous internal self-calibration. The device draws a nominal 330 A.

Low-power, low-voltage operation, and a simple serial interface make the CS5540 an ideal device for low-cost, power-conscious DC measurement applications.
