MAX921CSA Description

Short technical summary and product information.

The MAX921CSA comparator from Maxim Integrated offers exceptional low-power performance, drawing less than 4μA of supply current. It is suitable for single-supply applications operating from +2.5V to +11V or dual supplies from ±1.25V to ±5.5V. The comparator includes an internal 1.182V ±1% bandgap voltage reference and supports programmable hysteresis.

 

Key features include TTL/CMOS-compatible outputs capable of sinking and sourcing current, a propagation delay of 12μs (at 10mV overdrive), and no switching crowbar current. The input voltage range extends to the negative supply rail. The MAX921CSA is available in an 8-pin SO package and is designed for applications such as battery-powered systems, threshold detectors, and oscillator circuits.

 

This comparator's design minimizes parasitic feedback, making it easier to integrate into designs. The continuous source current capability of up to 40mA is notable for its low-power profile. Its operating temperature range is 0°C to 70°C.
