Its 3.5 ns maximum propagation delay sets the timing budget for the signal path: from an input overdrive condition to a valid output level, the comparator settles within this window, which defines the maximum clock rate the downstream logic can sample at without missing a transition. The complementary differential ECL open-emitter outputs drive 50-ohm terminated lines directly — the 30 mA typical output current is sufficient to swing a terminated ECL rail without an external buffer. ## Noise rejection and threshold accuracy 90 dB typical CMRR means the comparator rejects common-mode noise on the differential inputs by a factor of roughly 31,600 — critical when sensing a small signal riding on a large DC offset, such as a current-sense resistor voltage in a motor phase. 70 dB typical PSRR attenuates supply ripple by 3,160×, so a 100 mVpp ripple on the -5.2 V rail translates to under 32 µV at the input — this keeps the threshold stable in a switching power-supply environment without additional post-regulation.","metaTitle":"AD96685BRZ Analog Devices Comparator with Latch, 3.5ns","metaDescription":"AD96685BRZ single comparator with latch, 3.5ns propagation delay, 90dB CMRR, 70dB PSRR.
