Clocking Multiple Amplifiers in Parallel
If there are multiple AD199x family amplifiers connected to the
same PV
derivatives) for each amplifier as previously described. Avoid
clocking amplifiers from similar but asynchronous clocks if
they use the same power supply because this can result in beat
frequencies.
PROTECTION CIRCUITS AND ERROR REPORTING
Thermal Protection
The AD1994 features thermal protection. When the die
temperature exceeds approximately 135°C, the thermal warning
error output ( ERR1 ) is asserted. If the die temperature exceeds
approximately 150°C, the thermal shutdown error output
( ERR2 ) is asserted. If this occurs, the part shuts down to
prevent damage to the part. When the die temperature drops
below approximately 120°C, the part returns to normal
operation automatically and negates both error outputs.

Overcurrent Protection
The AD1994 features over current or short-circuit protection. If
the current through any power transistors exceeds approximately
4 A, the part enters a mute state and the overcurrent error
output ( ERR0 ) is asserted. This is a latched error and does not
clear automatically. Restore normal operation and clear the
error condition by either asserting and then negating RESET or
by asserting and then negating MUTE .
