Product details

7 ns comparator for high-speed threshold detection

The Maxim Integrated MAX961EUA+ is a single, general-purpose comparator from the Beyond-the-Rails™ family. It delivers a 7 ns propagation delay, making it suitable for high-speed signal conditioning, zero-crossing detectors, and overcurrent/overvoltage fault triggers in control loops. The 3.5 mV of built-in hysteresis eliminates output chatter near the trip point without external positive feedback resistors — a clean edge every time. Outputs are CMOS, complementary, and TTL-compatible.

Supply and signal integrity

Typical CMRR of 80 dB and PSRR of 86.02 dB give this part decent immunity to common-mode shifts and rail ripple. In a motor-drive or power-converter environment where the ground plane bounces, those numbers keep the threshold stable.

Housed in an 8-pin uMAX/uSOP (3 mm × 3 mm body), the MAX961EUA+ takes minimal board area. Surface-mount assembly only — no through-hole variant.

The ROHS3 declaration covers the full bill of materials — no red phosphorus or restricted phthalates in the mold compound.

Frequently asked questions

What is the propagation delay of MAX961EUA+?

The propagation delay is 7 ns maximum. That is the time from the input crossing the threshold to the output switching — fast enough for high-speed comparator applications like overcurrent detection and zero-crossing circuits.

Is MAX961EUA+ RoHS compliant?

Yes, the MAX961EUA+ is ROHS3 compliant. No restricted substances above the exemption thresholds.

Does MAX961EUA+ have hysteresis?

Yes, the MAX961EUA+ includes 3.5 mV of built-in hysteresis. This prevents output oscillation when the input signal is near the threshold, eliminating the need for external positive feedback resistors.
