What this dual comparator brings to the board
With a 450ns propagation delay, it's fast enough for most control-loop and signal-conditioning tasks — not for high-speed data streams, but solid for relay drivers, overvoltage/undervoltage lockouts, and window comparators. The ±3mV hysteresis is built in, which saves you two resistors per channel and keeps the output from chattering on noisy signals.
Low-power edge for field and battery gear
The industrial temperature range (-40°C to 85°C) covers factory-floor cabinets, outdoor telecom enclosures, and engine-bay-adjacent electronics. No need to derate for ambient heat in a panel — it's rated for the full span.
Sourcing and lifecycle — no LTB surprises
The MAX990EUA+T carries an Active lifecycle status per the manufacturer. RoHS3 compliant, so it passes the EU directive for lead-free assembly without an exemption hunt.
