ADS8519: Digital IO

BJ Han
Expert 2035 points

Part Number: ADS8519
Other Parts Discussed in Thread: ADS8681, ADS8685, ADS8689

Dear TI,

I am doing circuit design review with SPI multiple communication.
If the IC does not communicate, I know that the part that supports high impedance in the MOSI line.

Thank you.

    Hi BJ,

    Thanks for choosing TI precision ADC, I'm not sure what your question is, but if you are considering a bipolar high voltage +/-10 or +/-5V input ADC, ADS868x family may be a good option for you, these ADCs are 16-Bit ADC with Integrated Analog Front-End also support more input ranges and higher performance. Please refer more information as below:

    • High Speed:
      • ADS8681: 1 MSPS
      • ADS8685: 500 kSPS
      • ADS8689: 100 kSPS

    • Software Programmable Input Ranges:
      • Bipolar Ranges: ±12.288 V, ±10.24 V, ±6.144 V, ±5.12 V, and ±2.56 V
      • Unipolar Ranges: 0 V–12.288 V, 0 V–10.24 V, 0 V–6.144 V, and 0 V–5.12 V
    • 5-V Analog Supply: 1.65-V to 5-V I/O Supply
    • Constant Resistive Input Impedance ≥ 1 MΩ
    • Input Overvoltage Protection: Up to ±20 V
    • On-Chip, 4.096-V Reference with Low Drift

    Thanks&Best regards

    Dale
