Maxim Integrated MAX923CSA+ Low-Power, Single/Dual-Supply Comparators

The Maxim Integrated MAX923CSA+ is a high-performance comparator that combines low power consumption with a wide single or dual supply voltage range, making it an ideal choice for battery-operated and portable applications. This comparator is designed to operate from a single +2.5V to +11V supply or from dual ±1.25V to ±5.5V supplies, providing designers with flexibility in a variety of system configurations.

Featuring a fast 240ns propagation delay while consuming only 60µA of supply current, the MAX923CSA+ is optimized for systems where power efficiency is crucial. This low power usage does not come at the expense of performance; the comparator maintains a high degree of accuracy and stability over temperature and supply variations.

The MAX923CSA+ offers a unique combination of features that enhance its versatility in different applications. It includes an internal voltage reference, a latch-enable feature, and a programmable hysteresis capability, allowing users to tailor the comparator's performance to their specific needs. The latch function enables the comparator to hold its output state, which is particularly useful in multiplexed systems or when a stable output indication is required.

This comparator is available in a space-saving 8-pin SOIC package, making it suitable for compact designs. Its robust design ensures reliable operation over the industrial temperature range of -40°C to +85°C, which is essential for applications in harsh environments.

Applications for the MAX923CSA+ are diverse and include battery monitoring, window comparators, A/D converters, zero-crossing detectors, and level shifting circuits. Its combination of low power, high precision, and flexible supply options make it a go-to component for engineers designing power-sensitive and space-constrained electronic systems.

With the MAX923CSA+, Maxim Integrated continues to demonstrate its commitment to delivering high-quality, energy-efficient components that meet the evolving needs of modern electronic designs.
