  • ADS1259-Q1: IBIS Model

    Part Number: ADS1259-Q1 I am looking for an IBIS model for ADS1259QPWRQ1.

  • ADS1259: Data invalid immediately after DRDY_N asserts. Must insert delay to get valid data.

    TI Thinks Resolved
    Part Number: ADS1259 Hello, I am using Pulse mode with continuous read. Everything is working well, I just can't reconcile the need for this delay with the datasheet. I am using a state machine in an FPGA, so I have good control over the timing. I found…

  • RE: ADS1259: Does not work with using a multiplexer

    Hi Ferdinand Wimmer, Thanks for providing additional information. Please let us know what you discover as you perform additional tests Also, I would recommend in the future to just send your code as-is. It is challenging to provide support if we are not…

  • ADS1259: /DRDY not always asserting at sampling rate

    TI Thinks Resolved
    Part Number: ADS1259 I'm trying to use the 3 TI ADS1259 24-Bit Analog-to-Digital Converters to simultaneous sample generated 60Hz sine waves. The ADS1259s are configured for Gate Mode 3600 SPS with 3 byte Read Continuous mode. The communication is 4MHz…

  • ADS1259: Input filter for ADS1259

    Resolved
    Part Number: ADS1259 For an application where the ADS1259 operates on a single +5V supply and the REFOUT (+2.5V) is tied to the AINN pin. If a low pass RC filter is placed before the AINP pin with R=50 Ohms and C=10nF (fc = 159,155 Hz), would this basically…

  • ADS1259: Timing to Exit Power Down ( tRHSC )

    Resolved
    Part Number: ADS1259 Other Parts Discussed in Thread: PGA280 Device: ADS1259BIPW Per the spec, to exit power-down mode, you would need to hold the RESET/PWDN pin high for at least 2^16 tCLK cycles, which is around 8.88 msec when using the internal oscillator…

  • ADS1259: wrong CONFIG0 data

    Resolved
    Part Number: ADS1259 Hello. Project details: STM32L4 MCU ADS1259 using Internal oscillator SPI seems to be working. I am able to read registers but CONFIG0 contains 0x25(00100101) instead of expected 10XX0101. If i write 00000100 to CONFIG0 i read back…
