CS5521 overview
CS5521 is a component documented by Cirrus Logic. The PDF description identifies it as "16-bit or 24-bit, 2/4/8-channel ADCs with PGIA." This guide condenses the most useful engineering information from the available PDF so that designers and sourcing teams can identify the checks that still need confirmation in the original document.

Specifications and operating details
The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.
- To permit selectable input spans of 25 mV, 55 mV, 100 mV, 1 V, 2.5 V, and 5 V, the ADCs include a PGA (programmable gain amplifier).
- The digital filters are designed to settle to full accuracy within one conversion cycle and when operated at word rates below 30 Sps, they reject both 50 Hz and 60 Hz interference.
- Relationship between Full Scale Input, Gain Factors, and Internal Analog** CHARACTERISTICS AND SPECIFICATIONS ANALOG CHARACTERISTICS (TA = 25° C; VA+, VD+ = 5 V ±5%; VREF+ = 2.5 V, VREF- = AGND, NBV = -2.1 V, XIN = 32.768 kHz, CFS1-CFS0 =.
- For the CS5528, the 25 mV, 55 mV and 100 mV rang es cannot be used unless NBV is powered at -1.8 to -2.5 V 8.
- Chop clock is 256 Hz (XIN/128) for PGIA (programmable gain instrumentation amplifier).
- Parameter Min Typ Max Unit Analog Input Common Mode + Signal on AIN+ or AIN- Bipolar/Unipolar Mode NBV = -1.8 to -2.5 V Range = 25 mV, 55 mV, or 100 mV Range = 1 V, 2.5 V, or 5 V NBV = AGND Range = 25 mV, 55 mV, or 100 mV (Note 7) Range =.
- For input ranges <100 mV and output rates ≥60 Sps, 16.384 kHz chopping frequency is used.

Engineering review checklist
- Verify supply range, input common-mode range and output swing at the required load.
- Check offset, bias current, noise, bandwidth, slew rate and stability for the intended feedback network.
- Review supply decoupling, source impedance, capacitive-load behavior and thermal limits in the final layout.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
