Hi Venkatesan,
thank you very much for making us aware of this error in the ADS1131 datasheet. The datasheet has been updated accordingly now.

Part Number: ADS1263 Other Parts Discussed in Thread: ADS1131 , ADS1231 Tool/software: Hello,
We are looking for a new ADC to use in some of our applications. Can you help with some options? Spec list is below:
EAU: 10000/year
Sigma-Delta ADC with…
Can I ask what you hope to gain by chopping the excitation polarity using AC excitation? You may not get the results you are expecting relative to the effort involved. AC excitation will only remove the error and offset of the load cell. It will not affect…
Noaman,
I think the ADS1231 (or even the ADS1131) could work in your application. These devices were designed with weigh scale applications in mind. There is even a evaluation module (ADS1X31REF) available. At the minimum, it would be worth downloading…
Hi Antonio,
Thanks for your post! I do not believe that ADS1672 would be a suitable replacement for the MAX11212 due to the difference in resolution (24b vs 18b), sample speed (625kSPS vs 120SPS), power (350mW vs 0.8mW) or pinout (64 vs 10).
Perhaps…
Hi Natesh,
See my comments in your other posting.

Devices such as the ADS1230 are fully integrated and you do not need external amplification as the PGA is built into the device…
Hi Amin,
For the ADS1232 the full-scale range (FSR) is +/- 0.5Vref/Gain. For a 3.3V reference you should see +/- 0.5*3.3V or +/- 1.65V. As the output of the ADS1232 is binary 2's complement, the positive range in codes is 0 to 0x7FFFFF. I'm not sure…
Hi Andreas,
If the ADS1231 is used as an example we find that with 5V excitation (and voltage reference) the full-scale range of the ADS1231 is 39mV (+/-19.5mV). With 1.8mV/V sensitivity and 5V excitation the maximum output voltage of the load cell…
Other Parts Discussed in Thread: ADS1231 , ADS1230 , ADS1131 , ADS1235EVM , ADS1231REF I'm at my wits end with the existing ADC setup (MCP3561 + MCP1501) due to poor performance and documentation, so I'm looking to find a replacement part which is easy…
Hi Yamaguchi-san,
TI has many different devices that can be used for load cell applications. Some of them are single-channel input devices and others have multiple input channels. Also resolution varies from 18-bit, 20-bit and 24 bit. Some of the devices…
