Part Number: ADS7828 What is the max. voltage range for the analog input channels ? is it 0V to Vdd + 0.2V ? OR 0V to Vref (2.5V) ?
The part # is ADS7828EB
Part Number: ADS7828 I am using ADS7828EB/2K5 in my design to measure external voltages but my readings fluctuate because the IC's Vdd (+5V) changes +- 0.1V. Is there a way I can measure Vdd or measure the chips internal voltage reference (2.5V) to then…
Part Number: ADS7828 Hi,
the read data of the ADS7828 is always 0x0 on every channel. (All Channels are connected to Voltages I can measure on the Inputs to the IC)
Here is the protocol:
Red = SCL
Blue = SDA
Green = Tristate activated
Yellow = SDA on…
Part Number: ADS7828 when I used ADS7828 IC, I have faced a "READING DATA" problem. below show how I wrote the firmware read the CH1 value , ( below shown part of code in my firmware , I2c Initiation and other begin code work well. )
uint8_t…
Part Number: ADS7828 Hi,
Regarding ADS7828 datasheet, the internal reference default to off when the ADS7828 power is on (PD1=0).
We need to have command to enable it (PD1=1) .
If we use 0xFC directly to read ADC CH7 (PD1=1) when power on, the first…
Hi Tom-san,
Sorry for the late reply. 0VIF is GND of IF(Interface) Power Supply.
The IF power supply is the power supply for the non-voltage contact input from the external device by the photocoupler. Please refer to the attached document.

Part Number: ADS7828-Q1 Hi,
The absolute maximum rating listed in the datasheet of ADS7828-Q1 for the input pins is as below -
Digital Input Voltage to GND ................................. –0.3V to +VDD + 0.3V.
When the ADC is OFF (not powered…
