The MAX9201EUE+ from Maxim Integrated packs four general-purpose comparators into a single 16-TSSOP package. The 86.02 dB typical CMRR and PSRR keep the threshold stable even when the supply rail or common-mode voltage shifts — useful in mixed-signal boards where the analog front-end shares a rail with switching regulators.
Runs off a single 4.75 V to 10.5 V supply, or a dual ±2.375 V to ±5.75 V rail. That covers the common 5 V and ±5 V analog supplies without a separate regulator. Input offset voltage maxes at 4 mV at ±5 V, and input bias current stays under 5 µA, so the comparator won't load down a high-impedance sensor output.
Package and mounting — board-fit note
Surface-mount 16-TSSOP with a 4.40 mm body width. Standard footprint, no exotic pad geometry.
