69 mm actual size CS5560/70/80 24-pin SSOP CS5560 High-Throughput Delta-Sigma A/D Converters CS5560/70/80 The CS556x/7x/8x family of 24- and 16-bit Delta-Sigma analog-to-digital converters combine the higher-bandwidth, low-distortion performance of SAR converters with high-resolution, lownoise performance typical of Delta-Sigma ADCs.
The breakthrough combination of 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), compared 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 DeltaSigma 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 comparison, 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 su...
