CS5510-ASZ

Analog To Digital Converters (ADC) Overview

The CS5510-ASZ is a 16-bit delta-sigma analog-to-digital converter (ADC) from Cirrus Logic, housed in an 8-pin SOIC package. It utilizes charge-balance techniques to achieve a linearity error of ±0.0015% FS and up to 17 bits of noise-free resolution. The device requires an external master clock input on the SCLK pin, supporting frequencies up to 130 kHz for increased throughput, though typically operated at 32.768 kHz for 53.5 Sps output word rate with >80 dB simultaneous 50/60 Hz line rejection. It operates from a single +5 V supply or dual supplies, consuming 2.5 mW in normal mode and 10 μW in sleep mode.

Analog To Digital Converters (ADC) Feature Summary

• 16-bit resolution with ±0.0015% FS linearity error
• External clock input via SCLK pin (up to 130 kHz)
• Differential bipolar analog inputs with ±80% VREF input range
• Low power consumption: 2.5 mW normal, 10 μW sleep

Analog To Digital Converters (ADC) Applications

• Weigh scale systems
• Process control instrumentation
• Industrial data acquisition

Analog To Digital Converters (ADC) Procurement Notes

Verify the ASZ suffix indicates lead-free packaging options as specified in the ordering information section. Confirm the specific variant matches the required resolution and clock configuration, as the CS5510 family includes variants with internal oscillators (CS5511/13) which are not functionally equivalent to the externally clocked CS5510.

Analog To Digital Converters (ADC) Selection Notes

Select the CS5510-ASZ when an external master clock source is available and 16-bit performance is sufficient. Unlike the CS5511/13, this model does not include an on-chip oscillator, requiring the system designer to provide a CMOS-compatible clock signal to the SCLK pin. Ensure the supply voltage configuration supports the required common-mode input range.

Analog To Digital Converters (ADC) Part Context

The CS5510 is part of the CS5510/11/12/13 family of low-cost, easy-to-use ΔΣ ADCs. While the CS5512/13 offer 20-bit performance, the CS5510 provides 16-bit accuracy. The 'ASZ' designation typically refers to the package type and environmental compliance (lead-free), distinguishing it from older non-compliant variants within the same electrical specification set.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional replacements within the same family include the CS5511-ASZ if an internal oscillator is preferred instead of an external clock source. Note that the CS5512/13 models offer higher 20-bit resolution but share similar interface characteristics. Verify pin compatibility and software register mapping if migrating between different bit-depth variants.
