Part Number: ADS1240 Other Parts Discussed in Thread: IVC102 , , ADS122C04 Hi Team,
Our customer is using IVC102 transimpedance amplifier for their product and would like to ask what ADC we could recommend to connect to it. Currently he is using LTC2485…
Hamid,
First, I would skip doing any calibration. Right now your calibration value is far off from what it should be. Normally this would be a value near 555559h. Instead, you're getting 4001BCh, which makes your output value 25% lower than expected…
Hi Mike,
Welcome to the E2E forum! The ADS1240 is single-cycle settling, so following the register write command to change the data output rate, the next transition of DRDY from high to low will signal a new conversion result is ready. The period of…
Hi Pablo,
Unfortunately you must provide a clock source for the ADS1240 as the ADS1240 cannot be operated by the SCLK alone. All internal analog circuitry is driven from the master clock source to the Delta-Sigma converter of the ADS1240. The SCLK is…
Other Parts Discussed in Thread: ADS1240 Dear Technical Support Team,
I have a question about ADS1240.
①/PDWN
Datasheet Page5 shows following about /PDWN, but it doesn't describe the detail.
Dose it keep the resister value?
How is the behavior…

Dear Technical Support Team,
I have some questions about ADS1240.
1.)
Datasheet shows following specs for AVDD=3V.
Dose it means that input fullscale range always 1.25V?
RANGE = 0…

For some device, the AGND should be connected with DGND together. But for some devices, the AGND can be connected to negative supply.
ABSOLUTE MAXIMUM RATINGS if ADS1240 is as following…
Mahesh, If you are able to send a schematic, would you be willing to post it? In particular, I'd like to know if the POL pin is low. If it is, then based on the scope photos, you have the wrong type of SPI running. If POL=0, then the data should be set…
Other Parts Discussed in Thread: ADS1240 I'm looking at ADS1240 datasheet http://www.ti.com/lit/ds/sbas173e/sbas173e.pdf page 21.
There is a high precision weight scale block diagram. I see one of the op amps there has positive feedback. Could it be…
