  • ADS7924:リファレンスが「Supply」 の場合、AVDDは一定でなくてもADIのスケールは維持されるか。

    Resolved
    Part Number: ADS7924 Tool/software: ADS7924 はリファレンスが「Supply」 になっています。デバイスは AVDD を加えた電圧から内部でリファレンス電圧を生成していすか。推奨動作電圧の範囲内の AVDD であれば何ボルトを加えても ADI のスケールは一定に維持されます。 具体的な例として、ADIのCH1に2.2Vを与えていれば、AVDDが5.5Vから2.2Vの範囲で変動しても、変換され出力されるデジタル値は同一ですか。例えばバッテリー駆動のケースです…

  • ADS7924: while switching between modes

    TI Thinks Resolved
    Part Number: ADS7924 Hi, I am using ADS7924 in my application for voltage monitoring and protection. I want to know what happens when switching between the modes, for example while running in Auto-Scan mode, If the mode is changed to Manual scan…

  • ADS7924: ads7924 I2C Running problem

    TI Thinks Resolved
    Part Number: ADS7924 Hi. I'm trying to run ads7924 using stm32f series. But i2c does not work so I check the i2c line. Between 0R, MCU side 3.3V but ads7924 side 0V. I set pull up setting of MCU internally . What is the problem? below is the circuit…

  • ADS7924: Problem with only 1 channel working

    Part Number: ADS7924 Hi Team, My customer is having an issue with the ADS7924 in that only CH0 reading is matching the real measurement. The following were the I2C communications between the host PC to the ADS7924, used Manual-single mode. Host…

  • RE: ADS7924: ADS7924 use for Bipolar signal measurement

    Hello, This device can only take in unipolar inputs. If you implement an DC offset on your input signal to shift it within the ADC input range, then this will work. Regards Cynthia

  • RE: ADS7924: startup timing

    Hello Nick, For start up, it is best to have AVDD ramp up first, or with DVDD. Analog and digital inputs should not be present before the device is powered on. Regards Cynthia

  • ADS7924: Analog input voltage?

    Resolved
    Part Number: ADS7924 In the abs max table of the datasheet, the abs max is listed as 300mV. Should this be ADD + 300mV instead? It appears the input shave both GND and VDD diodes, correct? In addition, any risk in have bias applied to input pins…
