  • DAC8871: settling time from +10V to -10V

    Part Number: DAC8871 Other Parts Discussed in Thread: OPA211 , THS4011 , OPA211A , THS4304 , OPA277 Hello, In the customer, the settling time from +10V to -10V is about 15us. -10V to 10V settling time is about 1us. In the datasheet, both settling time is about…

  • DAC8871: voltage drift at voltages lower than -8.5V

    Part Number: DAC8871 Hello, I have a dac8871 that is being used with an SBC. I'm using the dac to send a signal to a galvo drive. My reference input values are at -10V to +10V. The DAC uses 16 bit resolution, and it works very well above -8.5V. However…

  • DAC8871: Odd behavior, as the DAC is approaching the limits of range it appears to be slipping bits.

    TI Thinks Resolved
    Part Number: DAC8871 This is at the full range of the DAC I am using the DAC8871 with a full range of +/-10 volts on the output. The following slides show the 10 volt output from the DAC, the 5 volt output from the DAC and the 0 volt output from the DAC…
