The invention provides a circuit for preventing common-mode latch-up of a full-differential operational amplifier, which relates to the field of integrated circuits. When the common-mode output of the full-differential operational amplifier is latched, an anti-latch protection circuit is triggered to work. When the low-level latch detection circuit detects that the common-mode output latch is at a low level, it controls the charging circuit to charge the output stage circuit, and releases the low-level latch state of the common-mode output; the high-level latch detection circuit detects that the common When the mode output latch is at a high level, the discharge circuit is controlled to discharge the output stage circuit, and the latch state of the common mode output high level is released. When the common-mode output of the fully differential operational amplifier releases the latch state and returns to the normal state, the anti-latch protection circuit does not work so as not to affect the operation of the differential operational amplifier. The invention can prevent the common-mode latch of the fully differential operational amplifier, and the anti-latch protection circuit is in a dormant state after the latch state is released, which does not affect the working performance of the fully differential operational amplifier and does not introduce additional power consumption.
