The CS5513 is low-cost, easy-to-use, ?S analog-to-digitalconverters (ADCs) which use chargebalancetechniques to achieve 16-bit (CS5510/11) and20-bit (CS5512/13) performance. The ADCs are availablein a space-efficient, 8-pin SOIC package and areoptimized for measuring signals in weigh scale, processcontrol, and other industrial applications.To accommodate these applications, the ADCs includea fourth-order ?S modulator and a digital filter. Whenconfigured with an external master clock of 32.768 kHz,the filter in the CS5510/12 provides better than 80 dB ofsimultaneous 50 and 60 Hz line rejection, and outputsconversion words at 53.5 Sps. The CS5511/13 includean on-chip oscillator which eliminates the need for an externalclock source.Low-power, flexible supply configurations, compact pinout,and ease of use make these products idealsolutions for cost-conscience and space-constrainedapplications.
