Ambient Scientific has invented industry’s first Digital Analog (DigAn™) AI  technology. DigAn™ AI is an advanced version of On-Chip Analog AI computing technology that provides ultra-high performance and efficiency of Analog AI with implementation and commercial advantages of Digital chips. The company demonstrated its innovative DigAn technology with its Industry’s lowest power On-Device AI solution for ‘Wake on Word’ and other On-Device AI applications. 


Ambient’s DigAn™ AI Processor computes an entire layer of neurons in a single clock cycle using custom Analog techniques, a task that takes several hundreds or even thousands of clock cycles in traditional implementations. DigAn™ uses standard digital transistors to implement its analog AI compute functions.Analog is a great fit for AI computing. However, prior implementations had severe limitations in accuracy and computing range – two important parameters for optimal AI solution. Ambient has eliminated these limitations. While prior implementations have struggled to achieve 8-bit accuracy, Ambient’s DigAn™ (Digital Analog) technology can achieve 32-bit accuracy. This is 16 million times more accurate in computer language.


Ambient’s first solution is targeted to Industry’s lowest power On-Device ‘Always-ON’ AI for ‘Wake on Word’ and Anomaly Detection applications. It uses only 80μW (microwatts) power or less for AI computing, which is 200x lower than industry standard and 2x-3x lower than recent advancements. In addition, Ambient has invented important components such as Ultra-Low Power Analog to Digital Converter (ADC) to ingest sensor data and Ultra Low Power clock generator (LPO) to enable chip operation without external host.

Founded in 2017, Ambient Scientific’s mission is to enable a portfolio of AI solutions that scales from tiny devices to large computer systems. The company’s grass root level innovations deliver high performance, ultra-low power DigAn™ neural processors, that are easy to program. The company’s ambition is to be #1 AI computing solution provider of the world. Ambient Scientific is headquartered in San Jose, California.
