Looking back at the price history of ADS1248 in the past two years, it can be roughly divided into three stages:
• From September 2021 to August 2022, soaring and falling: Starting from September 2021, the price of ADS1248 began to soar from 90 yuan, and remained at a high price of 550 yuan from February to May 2022. Subsequently, it started to fall, reaching 180 yuan in August 2022.
• From August 2022 to January 2023, a brief resurgence: Starting from August 2022, the price soared from 180 yuan to 550 yuan within two months. However, the high price only lasted for one month before it began to decline continuously. By January 2023, it had fallen to 250 yuan.
• From January 2023 to August 2023, it soared to an all-time high price and then fell back to its original form: In the first four months, ADS1248 was on fire, soaring from 250 yuan to an all-time high price of 1,000 yuan. Subsequently, it gradually fell and currently stands at 220 yuan.
ADS1248IPWR received more inquiries in the market in July and August 2023, but the actual trading volume was not as "busy" as it seemed. This material has been in demand since the end of this year. The market price after the year was around 500 yuan. In April and May, the price had soared to 1,000 yuan. However, according to market news, the actual price that customers could accept at that time was very low.
Taken together, the demand for ADS1248IPWR has not shown any obvious signs of outbreak. The surge in inquiries may be due to the chip market's long drought. When the market is cold, everyone always doesn't want to miss any opportunity to make a deal. There is a certain demand for this material. But compared with the rising popularity, there are some bubbles.
We can reduce the power consumption of ADS1248IPWR by the following ways
1. Select the appropriate sampling rate and resolution
The power consumption of ADS1248IPWR is related to the sample rate and resolution settings. Reducing the sample rate or selecting a lower resolution can reduce power consumption. Depending on the application requirements, if the highest precision measurement is not needed, we can choose a lower sample rate or resolution.
2. Use low power mode
If the application allows some delay or intermittent data acquisition, we can utilize the low power modes of the ADS1248IPWR, these modes usually include standby mode, hibernation mode, and so on. In these modes, the power consumption of the device is significantly reduced.
3. Turn off unused functions
The ADS1248IPWR may have a variety of functions, such as internal reference voltage, temperature sensors, and so on. If some functions are not needed in the application, we can turn off these functions through configuration to its reduce power consumption.
4. Reduce communication frequency
When communicating with ADS1248IPWR through SPI interface, we try to minimize the number and frequency of unnecessary communication. Communicating only when you need to read data or configure the device can significantly reduce power consumption.
5. Optimizing power management
We need to make sure that the power supply voltage provided to the ADS1248IPWR is stable and that we try to avoid power fluctuations. Also, we can consider using a power switch or dynamic power management strategy to power the ADS1248IPWR only when needed.
