This product is a CMOS A/D converter with a maximum sampling rate of 4 kSps and a 6-pole low-pass Gaussian filter. It can be selected as a unipolar/bipolar range, and its power consumption is 25 mW-10 µW.
The CS5501 (16‑bit) and CS5503 (20‑bit) are CMOS A/D converters designed for low‑frequency signal measurement in physical, chemical, and biological applications. They feature a 6‑pole low‑pass Gaussian filter, on‑chip self‑calibration, and flexible serial interfaces, including UART support on the CS5501.
The document details analog and digital performance parameters, power consumption, recommended operating conditions, and switching characteristics. It also includes system calibration specifications and layout information for the evaluation board.
