MAX9022 Datasheet | Analog Devices

Description The MAX9021/MAX9022/MAX9024 single/dual/quad parators are optimized for low-power consumption while still providing a fast output response. They are designed for single-supply applications from 2.5V to 5.5V, but can also operate from dual supplies. These parators have a 3μs propagation delay and consume 2.8μA of supply current per parator over the -40°C to +125°C operating temperature range. The bination of low-power, singlesupply operation down to 2.5V, and ultra-small footprint makes these devices ideal for portable applications. The MAX9021/MAX9022/MAX9024 have 4m V of built-in hysteresis to provide noise immunity and prevent oscillations even with a slow-moving input signal. The input mon-mode range extends from the negative supply to within 1.1V of the positive supply. The design of the parator-output stage substantially reduces switching current during output transitions, eliminating power-supply glitches. The MAX9021 single parator is available in tiny 5-pin SC70 and SOT23 packages. The MAX9022 dual parator is available in 8-pin SOT23, μMAX®, and SO packages, and the MAX9024 quad parator is available in 14-pin TSSOP and SO packages.
