DIAGNOSTIC COIL DRIVER

The diagnostic coil can be used to verify the sensitivity of the

ADAF1080 by applying a known reference current between the

DIAG+ and DIAG− pins and measuring the output with and without

the reference current. Figure 55 shows a typical discreet circuit to

generate the reference current using the VDIAG reference voltage

and an RDIAG reference resistor.

Figure 55. Diagnostic Coil Driver Example

When using multiple ADAF1080 sensors, a single diagnostic coil

driver circuit can be used to drive all the diagnostic coils in series

by connecting the DIAG+ and DIAG− pins of the sensors in a

daisy-chain fashion.

Figure 56 shows an example of daisy chaining multiple ADAF1080

devices together using a common diagnostic coil driver.
