Product details

The MAX918ESA+ is a single comparator with an integrated voltage reference, part of the Beyond-the-Rails™ series. It operates from a 1.8V to 5.5V supply rail, drawing a maximum quiescent current of 1.6µA. The open-drain output with 4mV hysteresis suits it for low-frequency threshold sensing — temperature alarms, undervoltage lockout, or battery-monitor trip points where the 120µs propagation delay is fast enough.

For small quantities or prototype builds, the same channel applies — no minimum order threshold beyond what the distributor sets.

Frequently asked questions

What is the nearest equivalent to MAX918ESA+?

The closest sibling is the MAX917ESA+, which differs primarily in hysteresis — the MAX917 has no internal hysteresis (it relies on external feedback), while the MAX918ESA+ has 4mV of built-in hysteresis. If your design needs the internal reference but can add external hysteresis resistors, the MAX917 is pin-compatible. For a drop-in replacement with the same 4mV hysteresis, the MAX918ESA+ is the target.

What is the output type and hysteresis of MAX918ESA+?

Output type is open-drain, and the built-in hysteresis is 4mV. The open-drain output requires a pull-up resistor to the desired logic rail — typically 10kΩ to 100kΩ for low-speed threshold sensing.

What is MAX918ESA+'s listed type and series?

The type is 'with Voltage Reference' — an integrated 1.236V ±1.5% reference is included on-chip. The series is Beyond-the-Rails™, Maxim's family of comparators that accept input voltages beyond the supply rails.
