CS5510/11/12/13 Overview
The CS5510/11/12/13 family of low-cost, easy-to-use, Delta Sigma analog-to-digital (A/D) converters use charge-balance techniques to achieve 16-bit (CS5510/11) and 20-bit (CS5512/13) 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 main clock of 32.768 kHz, the filter in the CS5510/12 family members provides better than 80 dB of simultaneous 50 Hz and 60 Hz line rejection and outputs conversion words at 53.5 Hz. The CS5511/13 family members 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.
