ADC is a bridge connecting the real world and the digital world, because it involves technology, circuit, system and other high technical barriers, its design is extremely difficult, known as the pearl in the crown of the analog circuit。
In order to precisely focus on industrial measurement, the company introduced a highly reliable, low-power Sigma-Delta ADC CS1238DME chip with an effective resolution of up to 20 via a programmable gain amplifier (PGA).7-bit (PGA=128), gain error 8ppm。Built-in temperature sensor and high precision oscillator with two differential input channels。
Accurate measurement is always the top priority of industrial measurement
In industrial production automation control, accurate measurement data is the basis, higher measurement accuracy, you can get smaller measurement error, and then improve the accuracy of production process parameters。Directly affect work efficiency and product quality, and even related to production safety。
At the same time, industrial production equipment often runs in a complex, harsh working environment, high temperature, high humidity, high vibration is its basic form。Modern factories even require 24 hours ×N non-stop shutdown, in equipment detection and control, signal measurement and other applications, the need for relevant components and the measured medium close contact, so it is necessary to ensure that the measurement instrument equipment in the material of high reliability and stable application。
Carefully built gauge level ADC with a focus on high-precision industrial measurement
CS1238DME is mainly aimed at industrial transmitters, pressure measurement, weighing equipment and other industrial applications requiring low power consumption, high precision measurement and multi-protocol industrial communication and interfaces。We provide cost-effective and reliable solutions for industrial control processes, liquid/gas chemical analysis, blood meters, electronic scales, intelligent converters, portable equipment and other market segments。
In terms of functional characteristics, CS1238DME realizes 24-bit differential input without loss of code, has low noise PGA, magnification support 1/2/64/128 four-speed selection, can realize a wider range of signal processing。Data output rate: 10Hz, 40Hz, 640Hz, 1.28kHz。Minimum power consumption 0.6mW, INL less than 0.0015%。
The CS1238 has a Power down function, which enables the SCLK to enter Power Down mode when it changes from low level to high level and remains above 100µs, where current consumption is below 0.1μA。When the SCLK returns to low level, the chip will return to normal operation。The highly integrated function of the chip allows engineers to design more flexibly according to the needs of the system, especially in applications with weak signals and limited space range, and can achieve low power operation of the system。
In addition, the CS1238DME uses more stable internal IP and frame materials, and is carefully crafted from the inside out to help engineers quickly design highly reliable products that meet industry standards。
