What this part is — comparator with a built-in reference
The MAX9026EBT+T is a single comparator from Analog Devices' Beyond-the-Rails™ family that integrates a voltage reference on-chip. That means one less external component to place and route — useful when board area is tight or the BOM count needs to shrink. It is a comparator first, but the reference gives it a self-contained threshold, so it can directly compare an input signal against a stable internal voltage without an external bandgap or resistor divider.
Key ratings and what they mean for your design
Supply voltage spans 1.8 V to 5.5 V single-supply. The 2.2 µA max quiescent current is the headline number for battery-operated gear. Built-in 4 mV hysteresis eliminates output chatter on slowly moving or noisy input signals without external positive feedback resistors — saves two passives and the associated PCB area. The open-drain rail-to-rail output lets you wire-OR multiple comparators or level-shift to a higher-voltage logic input by pulling up to the desired voltage. Input offset voltage is 5 mV max at 5 V, and input bias current is 0.001 µA typical — negligible for most signal conditioning loops. CMRR is 50.45 dB typical, PSRR is 60 dB typical, both adequate for a threshold detector in a moderately noisy environment.
Package and environment
Housed in a 6-WLP (wafer-level package). That footprint suits compact portable devices, wearables, and sensor modules.
Lifecycle and sourcing
The MAX9026EBT+T carries an Active product status per the manufacturer — no end-of-life notice, no last-time-buy window. The part is ROHS3 compliant. Availability and current pricing confirmed at quote time.
