Note: Devices designated as EPU are typically early in their characterization process prior to finalizing all electrical and process
specifications. Specifications are subject to change without notice.
Notes:
1. Assure Vctrl never exceeds Vd during Bias ON and Bias OFF sequences and
Bias ON
1. Disable the PPG source
2. Set Vdt = 0V Vctrl = 0V and Vg = 0V
3. Set Vg =-1.5 V
4. Increase Vdt to 8V observing Id.
5. Set Vctrl = +1.0 V
6. Make Vg more positive until
7. Enable the PPG source
8. Adjust Vctrl for Vo = 8Vpp
9. Adjust Vg for 50% crossover
during normal operation.
- Assure Id = 0mA
- Id should still be 0 mA
- Typical value for
- Vin = 2 Vpp
Vg is -0.3 V
4-8V Driver Application
Idd = 175mA
Bias Procedure
for
.
Bias OFF
1. Disable the output of the PPG
2. Set Vctrl = 0V
3. Set Vdt = 0V
4. Set Vg = 0V
