The CS5510/11/12/13 are low-cost, easy-to-use, ΔΣ analog- to-digital converters (ADCs) which use chargebalance techniques to achieve 16-bit (CS5510/11) and 20-bit (CS5512/13) performance. The ADCs are available in a space-efficient, 8-pin SOIC package and are optimized for measuring signals in weigh scale, process control, and other industrial applications. To accommodate these applications, the ADCs include a fourth-order ΔΣ modulator and a digital filter. When configured with an external master clock of 32.768 kHz, the filter in the CS5510/12 provides better than 80 dB of simultaneous 50 and 60 Hz line rejection, and outputs conversion words at 53.5 Sps. The CS5511/13 include an on-chip oscillator which eliminates the need for an external clock source. Low-power, flexible supply configurations, compact pinout, and ease of use make these products ideal solutions for cost-conscience and space-constrained applications.
