It's designed for applications where board space is tight and power budgets are lean — the quiescent current maxes out at 5µA per the datasheet typical column, making it a natural fit for battery-monitoring, threshold-detection, and window-comparator circuits in portable or always-on equipment. The output stage is CMOS with rail-to-rail swing and TTL-compatible levels, so it interfaces directly with logic inputs without a pull-up resistor. Propagation delay is 8µs maximum — fast enough for most supervisory and sensor-conditioning loops, though not intended for high-speed switching or clock recovery. ## What the key ratings mean for your BOM The 4mV internal hysteresis cleans up slow-moving or noisy input signals without external positive feedback components. Input offset voltage is trimmed to 1mV maximum at 5V, which sets the practical resolution floor for the comparison point. Combined with 100dB CMRR and 80dB PSRR, the trip voltage stays stable across the 2.5V to 5.5V supply range and common-mode shifts — important when the comparator is powered from an unregulated battery or a noisy switching rail. Input bias current is a microscopic 0.003µA maximum at 5V, so high-impedance sources like a voltage divider using megohm resistors won't see significant loading error. That's the spec that lets you use large resistor values to keep the divider's self-discharge negligible in a battery-powered system. ## Temperature grade and environment Rated for the full -40°C to 125°C operating range, this part is suited for industrial control cabinets, automotive cabin electronics, outdoor telecom gear, and engine-bay-adjacent modules that see thermal cycling. The SOT-23-8 package's low thermal mass means it tracks ambient quickly — no significant self-heating at 5µA draw. ## Sourcing and lifecycle The part carries an Active product status with ROHS3 compliance.","metaTitle":"MAX9022AKA+T Dual Comparator, 4mV Hysteresis, SOT-23-8","metaDescription":"Maxim Integrated MAX9022AKA+T dual general-purpose comparator in SOT-23-8. 5µA quiescent, 1mV offset, 100dB CMRR, -40°C to 125°C.
