Atom Semiconductor’s chip products are mainly divided into two major product lines: ADC chips for analog sensors and general electronics, and digital sensor chips for new IoT applications.
Temperature and Humidity Digital Sensor Chip
Atom digital temperature and humidity sensor chip is a new generation of temperature and humidity sensor IC. Equipped with a newly designed CMO Senser chip. In addition to capacitive relative humidity sensor and band gap temperature sensor, the chip also contains an amplifier, A/D converter, OTP memory and digital processing unit.
Pressure Digital Sensor Chip
Atom pressure digital sensor chip is a new technology of pressure digital sensor chip. The pressure sensing and touch functions are integrated on a chip, which is different from the existing resistive, capacitive and piezoelectric sensor chip. It can achieve high-precision, low-power consumption and other characteristics.
Optical Digital Sensor Chip
Atom optical digital sensor chip is a new low-power optical sensor chip. The device has built-in multiple sensors and has a high degree of analog integration. Supports red/green/blue (RGB) light signal detection, ambient light (ALS) detection, proximity detection, and infrared (IR) signal and temperature information measurement. The high integration feature effectively reduces the system cost, saves multiple external components, and greatly simplifies the design.
High-Resolution ADC’s
High-Resolution ADC is an oversampling ADC. Through the design of SD modulator, high noise suppression is achieved under over-sampling, so as to achieve high precision. The control of noise is a technical challenge for SD ADC design. High-precision SD ADC chips usually require greater power consumption.
High-Speed ADC’s
High-Speed ADC is a low oversampling rate ADC, which can achieve a higher sampling rate than SD ADC. Through the low-noise design of the capacitor array and the core circuit, the SAR ADC can also achieve a high accuracy of about 16 bits. Combined with a MHz sampling rate, SAR ADC can become a high-precision quantization choice for many sensors and general electronic systems.
