Synaptics, Inc. is an American neural network technologies and computer-to-human interface devices development company based in San Jose, California.

[8] In 1992, the company used the pattern recognition techniques it developed to build the world's first touchpad for laptop computers that allowed users to control the cursor and click with no additional mechanical buttons.

[10] In October 2006, Synaptics provided a live demonstration of the Onyx, a concept smartphone with a color touchscreen enabled by its ClearPad touch controller technology.

[40][41] In July 2017, Synaptics acquired Conexant Systems, an Amazon Alexa partner that creates voice and audio software and silicon products for smart homes.

[47][50] In December 2021, the company acquired DSP Group for $538 million, integrating voice and vision artificial intelligence (AI) capabilities into its portfolio and strengthening its wireless offerings with ultra-low-energy (ULE) enabled security applications[51][52] In February 2022, Synaptics sold its headquarters and North San Jose campus for $58 million.

[54] In 2024, Synaptics introduced a platform based on its neural network processing technology for developers of Edge AI products.

[55] Synaptics was founded as an AI-focused company to develop chips that utilize neural networks to mimic human brain functions.

[59] In 1991, Synaptics researchers patented an enhancement of the "winner-take-all" circuit, originally developed by John Lazzaro at the University of Colorado.

[60] The circuit functions as a selector within a network of processors or neurons, identifying and amplifying the strongest signal based on fundamental physics principles.

[60] The patent introduced a method for dynamic recalibration of neurons, where the system self-tests against a reference pattern, adjusting biases by strengthening weaker signals and reducing overly sensitive ones.

[52][46] In 1992, Synaptics introduced a chip designed to read magnetic characters on checks, notable for its higher accuracy and speed in handling poorly printed text compared to conventional technologies.

[56] In the automotive industry, Synaptics has developed technology that enables drivers to adjust heating controls on touch screens while wearing thick gloves in freezing temperatures.

[64] Synaptics acquired DisplayLink in 2020, adding that company's hardware technology for docking stations and video conferencing, and software for graphics connectivity to its products.

[48] It also develops wired connection products such as converters for USB Type-C to HDMI or DisplayPort, for high resolution video display.

[66] Synaptics continues to develop laptop computer touchpads and fingerprint biometric technology, and other types of touch sensors and display drivers.

[67] In 2016, Synaptics developed the FS9100, a fingerprint sensor that can function accurately beneath up to one millimeter of glass, making it easier to integrate under a device's display.
