Product details

Single comparator with latch — 5.5ns propagation delay

Its 5.5ns maximum propagation delay makes it suitable for timing-critical threshold detection, line receivers, zero-crossing detectors, and pulse-width discriminators where the output must settle before the next clock edge. The latch input freezes the output state, allowing the comparator to sample an analog level and hold it for subsequent digital capture — useful in sampled-data systems and peak detectors.

Complementary, TTL outputs drive standard 5V or 3.3V logic families directly. The 85dB CMRR and 73dB PSRR mean the comparator rejects common-mode noise on the inputs and supply ripple — important when the part sits near a switching regulator or in a motor-drive environment where ground bounce is present. Single-supply operation from 3V to 5V eliminates the need for a negative rail, simplifying the power tree. The 10mA quiescent current (max) is modest for a 5.5ns comparator — the speed comes from the process, not from burning extra bias current.

Frequently asked questions

What is the propagation delay of AD8611ARZ-REEL7?

The maximum propagation delay is 5.5ns. This is the time from the input crossing the threshold to the output reaching a valid logic level — critical for timing closure in high-speed signal chains.

What is a direct equivalent or replacement for AD8611ARZ-REEL7?

The AD8611ARMZ-REEL is a functional equivalent: same 5.5ns delay, same 85dB CMRR, same latch and TTL output, but in an MSOP-8 package. The tube-packed AD8611ARZ is electrically identical — only the shipping medium differs.

What package does AD8611ARZ-REEL7 come in?

It comes in an 8-SOIC package (0.154", 3.90mm Width) on Tape & Reel. The supplier device package is 8-SOIC.

Is AD8611ARZ-REEL7 RoHS compliant?

Yes, it is ROHS3 compliant.
