General Description
The CS5510/11/12/13 are low-cost, easy-to-use,
Σ
An-
alog-to-Digital Converters (ADCs) which use charge
balance techniques to achieve 16-bit (CS5510/11) and
20-bit (CS5512/13) performance. The ADCs are avail-
able 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 Hz. The CS5511/13 include an
on-chip oscillator which eliminates the need for an exter-
nal clock source.
Low power, a flexible supply, a compact pinout, and
ease of use make these products ideal solutions for cost
conscience and space constrained applications.
