| The LED driver ICs have been designed to start up directly from the high-voltage supply by an internal JFET current source and incorporate all required protection features. |
| The new ultra-high voltage process will include JFET and depletion mode LDMOS for start-up and low on resistance LDMOS for power devices. |
| The JFET process is a proprietary process developed by BAE Systems. |
| With JFET inputs, the AD8220 in-amp achieves a guaranteed input bias current of 20 pA, maximum, and 4 pA, typical. |
| The use of a JFET as the amplifying element will prove beneficial for use in low phase noise oscillators due to its low flicker noise. |
