CS5580 Datasheet | Cirrus Logic

features provides designers of precision instrumentation, such as industrial process controllers, laboratory instrumentation, medical instrumentation, and high-speed weighing systems, with a significantly higher level of measurement accuracy, lower noise and higher throughput. The CS556x provides a much higher level of noise suppression than SAR converters, resulting in higher accuracy conversions and reduced post-conversion processing. The family features DNL error as low as ±0.04 LSB typical (CS5571), pared to ±1 LSB typical within SAR converters. In addition, the single-clock latency digital filter allows conversion-rate switching of the input with no loss in throughput. The CS556x’s high-throughput precision performance stands out among high-resolution Delta Sigma converters. With near-flat digital FIR filter characteristics, the CS556x product line achieves unrestricted, wide-bandwidth signal throughput usually seen only in higher-speed SAR converters - at resolutions up to 24 bits. With this flat filter, output data is a 1:1 representation of the input signal across the entire frequency range, up to the sampling rate of the converter. In parison, most Delta-Sigma converters utilize Sinc filters, which attenuate the signal at specific frequencies. Other additional key features of the CS556x include: - High-impedance buffered inputs that simplify external circuitry; - Fully differential inputs that provide the best possible noise rejection and dynamic accuracy, with the ability to measure bipolar signals; and - Self calibration to ensure superior measurement accuracy over variations in supply and temperature. A flexible serial interface eases connections to a variety of microcontrollers without external ponents (includes slave and self-sequencing master modes). .cirrus.
