Part Number: ADS7828-Q1 Other Parts Discussed in Thread: TLV9001-Q1 Tool/software: Hi TI
I'm working with the ADS7828-Q1 ADC and utilising the internal 2.5V reference provided on the REF OUT pin.
I have a thermistor that I am measuring the resistance…
Part Number: ADS7828 Tool/software: Dear TI Team:
We have ADS7828EB/2K5 in our design.
1. Could you pls review the SCH attahed, Thanks
2. Any layout suggestion or Tips for the PCB layout?
3. Is there any restrict for the Channel input series resistor?…
Part Number: ADS7828 Tool/software: There is no local reset for this I2C I/O expander. I am planning to pull the VCC low momentarily in case there is a latchup in the I2C communication. Is this an issue if the SDA/SCL and input pins are driven? Do I…
Part Number: ADS7828-Q1 Tool/software: need TI FAE support for Lixiang warranty about ADS7828E -40 ° booting abnormal issue ， please share us FAE contract window . Thanks ~
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 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…
