MAX987EUK+T

MAX987EUK+T is a high-speed, micropower, low-voltage, rail-to-rail I/O comparator. Internal hysteresis ensures clean output switching, even with slow-moving input signals. The output stage’s unique design limits supply-current surges while switching, virtually eliminating the supply glitches typical of many other comparators. Applications include portable/battery powered systems, mobile communications, zero-crossing detectors, window comparators, level translators, threshold detectors/discriminators, ground/supply sensing, IR receivers, digital line receivers.

• Push-pull output stage sinks and sources 8mA current
• Unique output stage reduces output switching current, minimizing overall power consumption
• 100μA supply current at 1MHz switching frequency
• No phase reversal for overdriven inputs
• Supply voltage range from 2.5 to 5.5V inferred from PSRR test
• Supply current per comparator is 53μA at TA=+25°C, VCC=5V
• Power-supply rejection ratio is 80dB typ at 2.5V ≤ VCC ≤ 5.5V
• Common-mode rejection ratio is 80dB typ at VCC=+2.7V to +5.5V, VEE=0V, VCM=0V, TA=-40°C to +85°C
• 5 pin SOT-23 package
• Operating temperature range from -40°C to +85°C
