8.1.3 Start-Up Settling Time

The ISOTMP35-Q1 can support either a step input power supply or a ramp power supply. When powering the device, consider the analog output settling time upon start-up. For a step VDD input, start-up time is approximately 1 ms.

The ISOTMP35-Q1 can support either a step input power supply or a ramp power supply. When powering the ISOTMP35-Q1, the user must keep in mind that the ISOTMP35-Q1 requires time to settle the analog output upon start-up:

  • For a step VDD input, start-up time is approximately 1 ms.
  • For a ramp VDD input with a ramp rate of 5 V/ms, start-up time is approximately 1.25 ms.

See Figure 6-8 and Figure 6-9 for more information.
