CS5513-BSZ

Analog To Digital Converters (ADC) Overview

The CS5513-BSZ is a 20-bit, single-channel delta-sigma analog-to-digital converter (ADC) from Cirrus Logic. It features an on-chip oscillator operating at 64 kHz, eliminating the need for external clock sources. The device provides a noise-free resolution of up to 17 bits with a linearity error of ±0.0015% FS. It supports differential bipolar analog inputs and operates within a supply voltage range of 4.75 V to 5.25 V. Power consumption is 1.9 mW in normal mode and 10 μW in sleep mode. The component is housed in an 8-pin SOIC package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'BSZ' against manufacturer documentation to confirm lead-free packaging status and temperature grade. Confirm availability as this component may be subject to end-of-life notices or discontinuation by the manufacturer.

Analog To Digital Converters (ADC) Selection Notes

Select the CS5513-BSZ when a 20-bit resolution is required without the complexity of managing an external master clock. Ensure the application can accommodate the variable output word rate (OWR) inherent to the internal oscillator, which ranges from 53 Sps to 159 Sps due to oscillator drift.

Analog To Digital Converters (ADC) Part Context

The CS5513-BSZ belongs to the CS5510/11/12/13 family of low-cost, easy-to-use delta-sigma ADCs. While the CS5510 and CS5512 require external clocks, the CS5511 and CS5513 variants integrate an on-chip oscillator. This family is optimized for industrial applications requiring high linearity and low offset drift.

Analog To Digital Converters (ADC) Replacement Considerations

The CS5511-BSZ is a functional substitute within the same family but offers 16-bit resolution instead of 20-bit. Verify that the reduced resolution meets the application's accuracy requirements before substitution.
