Hello, the ADS131E0x is perfectly suited for economic metering applications. We already used it in a triaxial vibration meter with an MSP430.
Now I have a new application which includes a lot of IIR filtering. The CPU load becomes critical with the MSP430 so that I have to adjut the data rate carefully . 8192 SPS would be too much for the CPU but 4096 SPS is too low for the signal to be measured. An optimum data rate would be 5000 SPS.
The only way to tune the data rate seems to be the external clock input. According to the data sheet the maximum frequency is 2.25 Mhz, unfortunately. The clock frequency for my 5000 SPS would be about 2.75 MHz.
Has anyone experiences with overclocking the device? Is there any other way to obtain intermediate values for the data rate?
