CS5510/11/12/13 16-bit and 20-bit, 8-pin ΔΣ ADCs Features  Delta-sigma Analog-to-digital Converter – Linearity Error: 0.0015% FS – Noise-free Resolution: Up to 17 Bits  Differential Bipolar Analog Inputs  VREF Input Range from 250 mV to 5 V  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 Consumption – Normal Mode, 2.5 mW – Sleep Mode, 10 μW  Low-cost, Compact, 8-pin Package  Lead-free Device Package Options General Description The CS5510/11/12/13 are low-cost, easy-to-use, ΔΣ analog-to-digital converters (ADCs) which use chargebalance 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 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 external clock source. Low-power, flexible supply configurations, compact pinout, and ease of use make these products ideal solutions for cost-conscience an...
