The CS5513 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 converter is 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 CS5513 family member include an on-chip oscillator, which eliminates the need for an external clock source. 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.
