The CS5529 is a 16-bit programmable ∆Σ ADC with a linearity error of 0.0015%FS and a noise-free resolution of 16 bits. It features a 2.5V bipolar/unipolar buffered input range, a 6-bit output latch, and eight selectable digital filters. It has a simple three-wire serial interface, system/self-calibration with R/W registers, and supports multiple power supply configurations. Additionally, it has low power consumption of only 2.6mW.
The CS5529 16‑bit delta‑sigma ADC from Cirrus Logic provides high linearity (0.0015% FS) and a noise‑free resolution of 16 bits. It features a 6‑bit output latch, eight selectable digital filters, and a three‑wire serial interface compatible with SPI and Microwire.
The device operates from single or dual analog supplies (e.g., +5 V/0 V or ±2.5 V) and offers low power consumption (2.6 mW). It is available in 20‑pin PDIP and SSOP packages and is rated for -40 °C to +85 °C operation.
