CS5513-BSZR

Analog To Digital Converters (ADC) Overview

The CS5513-BSZR is a 20-bit delta-sigma analog-to-digital converter (ADC) from Cirrus Logic, featuring an integrated on-chip oscillator. It provides differential bipolar analog inputs with a linearity error of ±0.0015% FS and noise-free resolution up to 17 bits. The device operates at output word rates between 16 and 326 Sps, depending on the internal oscillator frequency variance. It supports supply configurations including single +5 V or dual supplies, consuming 2.7 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 'Z' suffix indicates lead-free packaging compliance. Confirm the 'BS' suffix corresponds to the specific temperature grade and package variant defined in the manufacturer's ordering guide. Check current lifecycle status as these components may be subject to end-of-life notices.

Analog To Digital Converters (ADC) Selection Notes

Select the CS5513 over CS5512 when an internal oscillator is required to reduce bill-of-materials complexity. Ensure the application can tolerate the output word rate variance (53 Sps to 159 Sps typical) inherent to the on-chip oscillator. Verify that the serial interface timing meets the microcontroller's capabilities for reading the 24-bit data word.

Analog To Digital Converters (ADC) Part Context

The CS5513 belongs to the CS5510/11/12/13 family of low-cost, space-efficient ADCs. It shares the same pinout and digital interface characteristics as the CS5512 but replaces the external clock requirement with an internal oscillator. This family targets cost-sensitive industrial applications requiring high-resolution DC measurements.

Analog To Digital Converters (ADC) Replacement Considerations

CS5512-BSZR requires an external master clock source instead of using the internal oscillator.
