Hi,Pins 51, 52, 62 and 63 are not bonded to anything; you should measure an open if you check those pins. In a preliminary datasheet these were going to be analog 1.8V, but there was an issue of...

Hi Laurent,Could you share the oscilloscope screenshot of the SPI communication error, as well as a schematic?Does your program hold /CS low? You may be getting a glitch on the SCLK. THe only way to...

Hi Kato-san,You can use the LDOO to power the 1.8 V for DVDD or you can use an external supply.The supplies (DVDD, AVDD, CPVDD) can be powered up at the same time.Where did you see Q2?Best Regards,dave

Usually the L value is quite stable, while Rp can be affected by temperature. I suggest that you check if the EVM is fastened well.To increase delta L, move the coil closer to the object, or use larger...

If I am feeding in data at 8K SPS and the Sample Rate Control (Address: 0001000) is set for Normal mode at 256Fs, it seems that MCLK should be 2.048MHz . I do not see how to resolve the SRx bits in...

Thanks!It is understood that conversion noise increases as reference voltage decreases, but what is the exact relationship between the two in the ADS1248. Linear? Exponential?

Hi Percy,The issue is most likely the clocking on the I2S lines. You are in slave mode with an MCLK of 10 mHz resulting in a sample rate of exactly 39062.5 kHz. Unless your LRCK input is at EXACTLY...
View ArticleForum Post: RE: TLV320DAC23 - clock question
Hi Percy,The sample rate scales exactly with MCLK so you can pick any values off the chart where Fs = MCLK/256.You can use the defaults with MCLK at 2.048 MHz. Putting the codec in master mode is...

Hi James,The relationship appears to be linear over temperature, but we don't have enough data with respect to noise over the full-input range to make a solid claim. There are a couple of interactions...
