Nixel 512

Fully differential 512 channel neural recording IC designed for 2024

The Nixel 512 chip is a low-noise and low-power mixed-signal programmable neural recording ASIC with 512 electrodes and 16-bit data path. Its uniform array of 256 purpose built active neural recording elements, called nixels, enables differential recording of neural signals with minimal noise.

With high recording density, adjustable controls, and simultaneous spike and local field potential recording, the Nixel 512 chip is tailored to meet the needs of any design, and is especially well suited for neural recording applications. Containing circuitry to record from 512 electrodes with ultimate flexibility in a footprint merely 16 mm2, the Nixel 512 chip offers unparalleled precision and performance for next-generation technologies.
