The CS5512 low-cost, easy-to-use, Delta-Sigma analog-to-digital (A/D) converters use charge-balance techniques to achieve 20-bit performance. The A/D converters 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 A/D converters include a fourth-order Delta-Sigma modulator and digital filter. When configured with an external master clock of 32.768 kHz, the filter in the CS5512 provides better than 80 dB of simultaneous 50 Hz and 60 Hz line rejection and outputs conversion words at 53.5 Hz. Low power, a flexible supply, a compact pin-out and ease of use make these products ideal solutions for cost-conscious and space-constrained applications.
