The CS5510/11/12/13 are low-cost, easy-to-use, ∆Σ analog-to-digital converters (ADCs) which use charge-balance 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 ∆Σ 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.
The CS5510/11/12/13 family are low‑cost, 8‑pin delta‑sigma analog‑to‑digital converters offering 16‑bit (CS5510/11) and 20‑bit (CS5512/13) performance. They are intended for weigh‑scale, process‑control and other industrial applications, featuring a fourth‑order modulator, digital filter, and flexible supply options.

The CS5510/11 achieves a typical linearity error of 0.0015 % full‑scale.
In normal operation the device consumes about 2.5 mW, while in sleep mode it draws roughly 10 µW.
The ADC can be powered with a single‑supply configuration of V+ = 5 V and V‑ = 0 V, and also supports multiple dual‑supply arrangements.
The CS5511/13 provides an output word rate of 107 samples per second, with up to a 50 % increase possible.
