Notes

1. Pulses of 7 V are allowed for less than 100 ms.

2. Minimum specified frequency at Tamb = 27 °C. For Tamb = 85 °C a typical value of 4 MHz is specified.

3. Not tested. Guaranteed by design.

4. Slew rates are measured between 10% and 90% of output voltage with a load of approximately 40 pF to ground.

5. Measured with RL = 1.2 kΩ, CL = 80 pF and VDDA2 = 5 V. The voltage drop at the output is less than 20 mV.

6. Referred to VHOME; nominal operating condition, direct control (DC = 1), VHOME programmed to 40.

7. The parameter is measured starting from code 4, due to a saturation effect for the first four codes.
