CS5511-ASZR

Analog To Digital Converters (ADC) Overview

The CS5511-ASZR is a 16-bit, single-channel delta-sigma analog-to-digital converter (ADC) from Cirrus Logic. It features an on-chip oscillator eliminating external clock requirements and supports differential bipolar inputs with a reference range of 250 mV to 5 V. The device achieves 0.0015% FS linearity error and up to 17 bits of noise-free resolution. Operating at output word rates up to 326 Sps, it consumes 2.5 mW in normal mode and 10 µW in sleep mode. Packaged in an 8-pin SOIC, it utilizes a serial interface for data retrieval.

Analog To Digital Converters (ADC) Procurement Notes

Verify the component status as the source indicates end-of-life or obsolete status. Confirm availability through authorized distributors as stock may be limited. Ensure the ordering suffix matches the required package and temperature grade specifications for the target application.

Analog To Digital Converters (ADC) Selection Notes

Select the CS5511-ASZR when an internal clock source is preferred over an external crystal or oscillator. This model is suitable for applications requiring 16-bit accuracy with low offset drift. Compare against CS5510 if an external clock is mandatory, or CS5512/13 if 20-bit performance is required.

Analog To Digital Converters (ADC) Part Context

The CS5511-ASZR belongs to the CS5510/11/12/13 family of charge-balance ADCs. It shares the same 8-pin SOIC footprint and digital interface characteristics as its siblings. The primary distinction within the family is the inclusion of the on-chip oscillator in the CS5511 variant compared to the external clock requirement of the CS5510.

Analog To Digital Converters (ADC) Replacement Considerations

CS5511-ASZ is the lead-free version of this component. For pin-compatible alternatives with different clocking requirements, consider the CS5510 series.
