Part Number: ADS1212 Hi,
My customer need assistance.
Wiring as follows: AinP connected to analog voltage input; AinN to grounding; AGnd is connected to analog ground; Vbias is floating; CS connected to MCU; DSYNC connected to + 5V; Xin input 2MHz active…

Dear, support team. Our customers are using Synchronizing Mutliple with Four ADS 1212. Writing 0xe 3 to command register byte 3 Pull up the DSYNC pin. Only one DRDY will assert early. The customer's figure uses DRDY and CLK inverted.…
Part Number: Hi team
I have questions about the offset calibration register and the full scale calibration register of ADS1212.
1. At the default condition(I mean, when this device is shipped from TI), are any calibrations done and are any calibration…
Part Number: It looks like, possibly, a register is rolling over in the correction algorithm. The Offset and Gain terms generated during the self calibration are on a continum, yet the A/D output is bistable. I either get X as an output or X+150. Never…

This has been an ongoing issue. Replacing the chip fixes the problem.
Here is a scope trace of the register write measured at the ADS1212 pins...
When I read it back, the bit is zero....

Hi Ryman,
The speed of the SCLK is dependent on the ADS1212 oscillator frequency. SCLK can be no faster than 1/10 of the fosc of the ADS1212. For a 2.5MHz clock, the SPI can be no faster than 250kHz. It can be slower however. For example, if the micro…
