Forum Post: ADS7038: Oversampling Function (OSR), Averaging, and Mode of Operation
Part Number: ADS7038 Tool/software: Hello E2E Experts, Good day. First, in the datasheet, it says that "in autonomous mode of operation, samples from analog input channels that are enabled in the AUTO_SEQ_CH_SEL register are averaged sequentially," does this means that the averaging is spanning over all the selected input channels? Also, my input bandwidth is 8kHz per channel, so if I want to oversample by 4x, it would be 32kSps per channel. If I want to average by 2, then the data rate per channel is 16kSps, correct? What is the best setup for this scenario (OSR setting, mode, etc.)? In addition, If the max sampling rate can handle it, I would like to use up to 4 chips (32 input channels). Can I share the same SPI port, with a separate CS to each ADC chip? Regards, TI-CSC

Forum Post: RE: ADS52J90: Analog input termination and coupling
Hi Corey, Because of ADC sampling circuit there will be high frequency glitch at the input . To absorb that glitch 50 ohm and 6.8pf is placed . This will form HPF to attenuate those glitches .These can be modified according to your needs . This corner should lie outside of your signal bandwidth . If you dont have this option this glitch can reflect back and effect next sample which effects SNR.

Adams, Again, we do not have anything like that. It sounds like you are looking for a custom FPGA solution so I would suggest contacting an FPGA vendor and work with them to develop your long term test solution. Regards, Geoff

Forum Post: RE: ADS8665: Writecommands (and 9-bit address)
The WRITE commands still doesn't quite makes sense to me. Let's say I want to write to the ALARM_H_TH_REG Register at addres 0x24 (0b0010 0100) Let's say I want to put 0xFF in INP_ALRM_HYST and 0x00FF in INP_ALRM_HIGH_TH. If I can only write 16 bits at a time, I'll have to do two writes. The will be 0x024 (0b0 0010 0100) The will be in bith cases 0x00FF (0b 0000 0000 1111 1111) So I how do I select which part of the register to write to? (I.e. because we can only write 8 or 16-bits at a time - we need a way to select where in the 32-bit register those 8 or 16 bits are written). Are there any examples? That may help me under stand this.

Forum Post: RE: TPL0102-100: Potentiometer and a timer
Dear Katlynne, I could make the circuit and according to the simulations it works properly. I have designed a ripple detector circuit that monitors ripple voltages and detects when the peak-to-peak ripple voltage exceeds 30mV. The final stage of this circuit is a comparator, which outputs a constant "1" when ripple is detected and "0" when there is no ripple. Now, I want to add a timer that will activate an alarm if the ripple persists for more than 20 seconds. I attempted to use a 555 timer for this purpose, but I am unsure how to trigger it correctly given that the comparator output is either always "1" or "0". I would greatly appreciate any help or suggestions on how to achieve this.

Forum Post: RE: ADS131M08: ADS131m08 SPI communication problems
Hi, i found the software examples in the site, under the adc software tab. I saw that my code had nothing wrong if compared to the ti routines, the problem was that my adc was defective. Substituting it with a new one solved the problem, the device now communicates without problems. Just a note, for proper SPI communication to work, i had to configure my master SPI with CLOCK = 0 and POLARITY = 0. With POLARITY = 1, (as the ADS131m0x datasheet suggest, if i m not wrong), i read only bad datas. Anyway all right. Thank You Kind Regards Emanuele Peruzzi
