Part Number: ADS1226 Hello,
We have an issue with random conversion and autocalibration times after startup.
In our design, we have a recovery mechanism that powers down the device for short duration (can be betweeen 200ms and 600ms).
The sequence is…
Part Number: ADS1226 Hi,
The datasheet does not specify how to acquire two channels consecutively.
We need to convert calibrated data from 2 channels in high resolution mode as fast as possible.
So the sequence we need to achieve is to have a cycle with…
Part Number: ADS1226 Hello,
It is not very clear for us when the self-calibration is needed.
We are using now the ADS1226 in high-resolution mode with the 2 channels active and performing a self-calibration each time we read a channel.
This gives use…
Part Number: ADS1226 Other Parts Discussed in Thread: ADS1225 , ADS1220 Hello TI engineers and all others,
I have some follow up questions to issue of incorrect operation of the ADS1225/ADS1226 when repeatedly powered-up as stated in this previous forum…
Part Number: ADS1226 Other Parts Discussed in Thread: ADS1220 Hi Team,
ADS1226 has two modes, high resolution and high speed mode. If customer select high speed mode the resolution could not be keep at 24bit, right? If so, what is the resolution at high…
Other Parts Discussed in Thread: ADS1226 , REF5050 , ADS1220 Hi TI Engineers and all,
We are using ADS1226 in our flow meter application.
Problem:
1. The conversion result is wrong and keeps wrong after power-up(confirmed with the multimeter). if power…
Other Parts Discussed in Thread: ADS1226 We wish to operate the ADS1226 converter with constant 2.4 - 3.0Vdc on the DVDD supply, and have the AVDD (5.0Vdc) switched off when the device is put into standby mode between samples.
Will the Self Calibration…
Other Parts Discussed in Thread: ADS1226 Hello,
I'm currently working on an project that uses an ADS1226 connected to a Cortex-M0 STM32F051.
I'm having some issues getting reliable data out of this device. Can you please tell me what is the correct…
Other Parts Discussed in Thread: ADS1226 Hi,
I am using the ADS1226 and run the first cycle after power up as a self calibration cycle. During the calibration time the ADC gives a digital output of 0x000000 and usually this lasts for up to 300ms as stated…
Other Parts Discussed in Thread: ADS1226 Hi,
I'm wondering what happens on startup with ADS1226?
ADS1226 has a different comportement when it startups with Vref with no potential, and when it startups with Vref potential no null.
When ADS1226 startups…
