GENERAL DESCRIPTION The CS5505/6/7/8 are very low power mono- lith A/D co nverters designed specifically for measurement of dc signals. The CS5505/7 are 16-bit converters (a four channel and a single channel version). The CS5506/8 are 20-bit ...

AIN1. The BP/UP pin is not a latched input. The BP/UP pin controls how the output word from the digital filter is processed. In bipolar mode the output word computed by the digital filter is offset by 8000H in the ...

Understanding Converter Calibration Calibration can be performed at any time. A calibration sequence will minimize offset errors and set the gain slope scale factor. The delta- sigma modulator in the converter is a differential modulator. To calibrate out offset error, ...

Analog Input Impedance Considerations The analog input of the CS5505/6/7/8 can be modeled as illustrated in Figure 8 (the model ig- nores the multiplexer switch resistance). Capacitors (15 pF each) are used to dynamically sample each of the inputs (AIN+ ...

Digital Filter Characteristics The digital filter in the CS5505/6/7/8 is the com- bination of a comb filter and a low pass filter. The comb filter has zeros in its transfer function which are optimally placed to reject line interfer- ence ...
Page 20
If the CS5505/6/7/8 is operated at a clock rate other than 32.768 kHz, the filter characteristics, including the comb filter zeros, will scale with the operating clock frequency. Therefore, opti- mum rejection of line frequency interference will occur with the ...
