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 Sps. The CS5511/13 include
an on-chip oscillator which eliminates the need for an ex-
ternal clock source.
Low-power, flexible supply configurations, compact pi-
nout, and ease of use make these products ideal
solutions for cost-conscience and space-constrained
applications.
