Product details

Low quiescent current — what 24 µA means for the BOM

Quiescent current maxes at 24 µA. That is the current the comparator burns just sitting there, no load. In a battery-powered sensor node or a loop-powered transmitter, that 24 µA is a meaningful slice of the sleep budget — it lets you keep the comparator alive for wake-on-threshold without draining the cell. Compare that to older bipolar comparators that pull half a milliamp or more; this part is the low-power pick for always-on monitoring.

Not automotive-grade (no AEC-Q100), but fine for commercial and industrial equipment that stays above -40°C. The 8-SOIC package is a standard footprint — easy to hand-solder or reflow, and widely second-sourced for board layout.

ROHS3 compliant.

Frequently asked questions

What are the alternatives to MAX985ESA+T?

Pin-compatible alternatives within the same general-purpose comparator family include the MAX985ESA+ (non-tape-and-reel) and the MAX986ESA+ (different hysteresis spec). For a direct drop-in with the same 450 ns delay and 24 µA quiescent, the MAX985ESA+T is the tape-and-reel variant; the MAX985ESA+ in tube packaging is functionally identical.
