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…
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…
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…

We are using the smbus2 library in Python to read data coming originally from a TMSC1108-Q1 current sensor (analog) which is sent through an ADS7828 ADC and communicated to a Raspberry Pi via I2C protocol . We defined an array of length…
Part Number: ADS7828-Q1 Other Parts Discussed in Thread: ADS7828 Hi, I am facing issues in I2C Communication with ADC IC ADS 7828. On my custom board, the microcontroller is connected to the ADC IC via an I2C isolator. Most of the time the I2C Communication…
Part Number: ADS7828 Hi,
ADS7828 is designed as 2nd source, however, the data format is different from main source. Customer needs a special bit or ID to identify ADS7828 then change calculation. does ADS7828 support vender or unique bit/ bytes to identify…

Hi.
Regarding ADS7828 that is an 8-channel ADC with I2C interface.
If in the schematic I'm going to have 8x 0/4~20mA current inputs using 8x the circuit below, where a 20mA output from sensors do generate 2V at the 100R sampling…
