  • ADS1259-Q1: Pulse withstand of the SPI pins

    TI Thinks Resolved
    Part Number: ADS1259-Q1 Tool/software: Hi, I'm using the ADS1259-Q1 in a high voltage battery application and I noticed some voltage spikes on he SPI mile between the uC and the ADS1259-Q1 when the contactors are closed that seem to be related to…

  • ADS1259: Unable to communicate with ads1259 and wrong data receiving

    Part Number: ADS1259 Tool/software: so i was trying to read the ADS1259 Using stm32F071 my spi configuration is hspi2.Instance = SPI2; hspi2.Init.Mode = SPI_MODE_MASTER; hspi2.Init.Direction = SPI_DIRECTION_2LINES; hspi2.Init.DataSize = SPI_DATASIZE…

  • ADS1259-Q1: ADS1259-Q1 capacitor between REFP and REFN

    TI Thinks Resolved
    Part Number: ADS1259-Q1 Other Parts Discussed in Thread: ADS1259 Hi, I'm using the ADS1259-Q1 part with it's own internal voltage reference. The datasheet says that I can leave the REFP and REFN pins unconnected or tied to AVDD is this case however reading…

  • ADS1259-Q1: Analogue input pin current rating

    Resolved
    Part Number: ADS1259-Q1 Hi, I'm using the ADS1259-Q1 and I would like to eliminate external voltage protection diodes in the analogue inputs to save cost and any measurement error these components may cause. The only thing stopping me is that the datasheet…

  • 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…

  • ADS1259: Does not work with using a multiplexer

    TI Thinks Resolved
    Part Number: ADS1259 Hi there, I'm already trying running this ADS1259 with a multiplexer. So far I could not get it running by using different multiplexer. As far as I just use one multiplexer and the same data on the others it works alright. After using…

  • 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…
