  • HSMC-ADC Bridge and ADS42LB69 EVM compatibility

    Other Parts Discussed in Thread: ADS42LB69 , ADS42LB49 I need to interconnect ADS42LB69 EVM with Arria V FPGA development kit ( www.altera.com/.../kit-arria-v-gx.html) from Altera. Arria V FPGA kit has HSMC connector on it. I need to use both the ADC channels…

  • RE: ADS124S08: Implementation of device for 8 thermistors and an RTD measurements.

    Hi nestor Garcia, There are a couple of resources available regarding temperature measurement. They are A Basic Guide to RTD Measurements and A Basic Guide to Thermocouple Measurements . There is also a Temperature Sensing Code Library that may be useful…

  • RE: ADS1242: ADS1242

    Hi Eduard Dubinin, Bob is out of the office this week so I will offer my support while he is gone Can you tell me if the buffer is enabled for your measurements? With the buffer disabled, the ADC input impedance will be typically 39kohm at a gain of 128…

  • RE: ADS1247: Stability Issue

    Resolved
    Hi Nimit Vachhani, A couple of questions / comments about the schematic: You show both a GND net and an AVSS net - are these connected somewhere? You have a lowpass filter on your inputs (S+ / S- pins) but not on the SENSE lines. Instead you only have…

  • RE: ADS1248: ADS1248 1/f Noise At Low Current Source Levels

    Hi Mike N Can you send us the data you are seeing in an Excel file? Preferably the raw ADC data? It would be useful to see both the "good" data using the 1kohm bridge and the "bad" data using the 10kohm bridge so we can compare -B…

  • RE: INA333: Can we generate a differential output signal using INA333 Cross-Connection Technique ?

    Hi Shkelqim, If I understood correctly, your bridge offers full-scale signal of +/- 20mV. The ADC for weight scales device you feature above, from another manufacturer, already integrates a programmable gain amplifier (PGA). According to your equation…
