  RE: REF3233: theta JC and theta JB for REF3233

  Hi Aosker, The REF3233 is NRD, is this a new design? Can we get them to switch to the REF3433? The REF3433 is P2P. The REF3433 is more accurate, has theta JC and theta JB, and it has a lower 1ku price. Can you confirm these and if the customer...

  RE: TMS320F28377D: configure 28377D 16bit differential ADC to uniploar

  Hi Boyuan, Feedback capacitor C1 introduces phase delay and that in turn causes the signals on the first cycle to be distorted. Maybe there's another reason for implementing the input network on the eddy current sensor this way? I am not familiar...

  RE: ADS1258: ADS1258IPHPREP

  Hi Mahesha, Thanks for sharing a PDF schematic with me! Is there any reason why you're not measuring the voltage across each of the RTDs deferentially and using a reference resistor (to make the measurement ratiometric), similar to the following...

  RE: TMS320F28379S: ADC buffer interface voltage

  Hi Ari, That really depends on how accurate you want the conversion results to be. Using VDDA as reference to VREFHI is possible but conversion results will not degrade. VDDA supply powers the analog blocks inside the chip and part of the analog block...

  RE: REF3233: The output voltage question for REF3233

  Hi Mickey, Table 1 on pg 9 of the REF3233 datasheet has recommended values for R1 and C1. The issue is that these values assume a fast rise time. The simplest solution would be to just replace the REF3233 with the REF3433. P2P stands for pin to pin...

  RE: LM4132-Q1: LM4132-3.3V reference produces up to 4.0V at the output during power-up!

  Or see section 10.2.2.3 in the datasheet of TI's REF3433: 10.2.2.3 VIN Slew Rate Considerations In applications with slow-rising input voltage signals, the reference exhibits overshoot or other transient anomalies that appear on the output. These...
