Product Overview
MAX9021AUK+T is a micropower, ultra-small, single comparator. It is optimized for low-power consumption while still providing a fast output response. The combination of low-power, single supply operation down to 2.5V, and ultra-small footprint makes this device ideal for portable applications. It has 4mV of built-in hysteresis to provide noise immunity and prevent oscillations even with a slow-moving input signal. The input common-mode range extends from the negative supply to within 1.1V of the positive supply. The design of the comparator-output stage substantially reduces switching current during output transitions, eliminating power-supply glitches. Applications include battery-powered portable systems, mobile communications, sensor-signal detection, photodiode preamps, digital line receivers, keyless entry systems, threshold detectors/ discriminators.
- No phase reversal for overdriven inputs, comparator output swings rail-to-rail
- Operating voltage range from 2.5 to 5.5V guaranteed by PSRR test
- Supply current per comparator is 2.8µA at VDD=5V, VSS=0, VCM=0, TA=-40°C to +125°C
- Input offset voltage is ±1mV at VDD=5V, VSS=0, VCM=0, TA=-40°C to +125°C
- Common-mode rejection ratio is 100dB typical at VSS ≤ VCM ≤ (VDD - 1.1V), VDD=5.5V
- Power-supply rejection ratio is 80dB typ at VDD=2.5V to 5.5V
- Propagation delay is 8µs typ at VOD=10mV, RL=10kohm, CL=15pF
- Hysteresis is 4mV typ at VDD=5V, VSS=0, VCM=0, TA=-40°C to +125°C
- 5 SOT23-5 package
- Temperature range from -40°C to +125°C
