Recently, the high-profile 2024 (18th) Beijing International Automobile Exhibition was held in BeijingChina International Exhibition CenterGrand opening。More than 1,000 well-known automobile brands and core parts companies around the world participated in the event, and 117 new cars were launched in the world, and various cutting-edge technologies were dizzying。Core Sea Technology (stock code: 688595) participated in the Beijing Auto Show for the first time with a number of its vehicle regulation product series。
Core Sea technology series products are located in"China Core Exhibition Area" of Intelligent Driving Future Exhibition Area E1-W03It covers a number of series such as high-performance MCU, PD fast charging, human-computer interaction and ADC。Among them, low-power SPI interface 18/16/12-bit vehicle gauge ADC chip CS1x1x series, and support multi-channel 12/13-bit vehicle gauge SAR ADC chip CS1795x series are the first public appearance, received the attention of the audience。
The first appearance of the car gauge ADC series
◎ Automotive-grade CS1x1x Series ADC with integrated high-precision reference and temperature sensors
The CS1x1x series Sigma-Delta ADCs are designed with low power consumption and integrated with theProgrammed gain amplifiers (PGA), voltage reference and high precision temperature sensors support 2V to 5.5V wide voltage supply range。The CS1x1x programmable gain amplifier (PGA) has an input range from ±102.4mV to ±6.144 V, can measure large and small signals in high resolution。The input multiplexer (MUX) allows measurement of two differential or four single-ended inputs。
In addition, the series also has two operating modes of continuous conversion and single conversion, and automatically shuts down after the conversion is completed in the single conversion mode, which can significantly reduce power consumption。Ultra-low operating current andMSOPThe package is ideal for power - and space-constrained applicationsSensor measurement applications, can be widely used in automotive BMS, ADAS, power system, OBC and other key parts。Product information of the CS1x1x series is as follows:
