CS5510/11/12/13

16-bit and 20-bit, 8-pin ΔΣ ADCs

Features

General Description

The CS5510/11/12/13 are low-cost, easy-to-use, ΔΣ 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.

 Delta-sigma Analog-to-digital Converter

– Linearity Error: 0.0015% FS

– Noise-free Resolution: Up to 17 Bits

 Differential Bipolar Analog Inputs

 V

Input Range from 250 mV to 5 V

REF

To accommodate these applications, the ADCs include

a fourth-order ΔΣ 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.

 50/60 Hz Simultaneous Rejection

(CS5510/12)

 16 to 326 Sps Output Word Rate

 On-chip Oscillator (CS5511/13)

 Power Supply Configurations:

– V+ = 5 V, V- = 0 V

– Multiple Dual-supply Arrangements

Low-power, flexible supply configurations, compact pi-

nout, and ease of use make these products ideal

solutions for cost-conscience and space-constrained

applications.

 Low Power Consumption

– Normal Mode, 2.5 mW

– Sleep Mode, 10 μW

 Low-cost, Compact, 8-pin Package

 Lead-free Device Package Options
