Phase Reversal Protection
Most industry standard JFET input single, dual, and quad
op amps (e.g., LF156, LF351, LF353, LF411, LF412,
OP-15, OP-16, OP-215, and TL084) exhibit phase reversal
at the output when the negative common-mode limit at the
input is exceeded (i.e., below –12V with
±15V supplies).
The photos show a
±16V sine wave input (A), the response
of an LF412A in the unity gain follower mode (B), and the
response of the LT1457 (C).
The phase reversal of photo (B) can cause lock-up in servo
systems. The LT1457 does not phase-reverse due to a
unique phase reversal protection circuit.
