Welcome to Intan Technologies, leader in the development of specialized integrated circuits for biological sensing.

We create innovative low-power microchips to acquire bioelectric signals such as EMG, ECG/EKG, ECoG, EEG, neural action potentials, and local field potentials. Our products are used by biomedical companies and research groups in more than 30 countries around the world.

We are pleased to announce the launch of our latest product line, the RHD2000 series digital electrophysiology interface chips. These revolutionary new devices integrate up to 64 low-noise amplifiers, programmable analog and digital filters, a 16-bit analog-to-digital converter, and an industry-standard digital SPI bus onto a single piece of silicon. Recording electrodes are connected to one side of the chip, and digital data streams out the other side.

By transforming weak electrode signals directly into a digital data stream, the RHD2000 replaces all analog instrumentation and digitizing circuitry in electrophysiological monitoring and data acquisition systems. The small size and low power consumption of this analog front-end (AFE) enables the miniaturization of front-end electronics for electrophysiology recording instruments, brain activity mapping systems, advanced prosthetic interfaces, and wearable or portable biopotential recording systems. To facilitate product development using these chips, we have recently released the RHD2000 USB evaluation system which is built around the open-source Rhythm USB/FPGA interface.

At Intan Technologies, our mission is to provide flexible, high performance microelectronic solutions for next-generation scientific, medical, and consumer devices that interface with biopotential signals. With years of expertise in both state-of-the-art microchip design and modern electrophysiology techniques, we have a deep understanding of the nature of biological signals and how best to acquire them using advanced integrated circuit technology.

Explore our existing products, see what some of our users have published using our technology, or contact us to discuss how our integrated circuits can help you operate at the interface between technology and biology.
