I am designing new circuit of out new product and i would like to use AD420.

But I can not understand external boost function circuit.

On your datasheet and application note, propose to use NPN transistor by using
external boost function.

But the MJD32C is not NPN transistor.

The MJD32C is PNP transistor.

Check your datasheet or application note and offer the right application
circuit please.


There is an error in the datasheet in the naming of this device – the customer
is correct the MJD32C is a PNP device.

This datasheet should state MJD31C – which is an NPN device.
