MAX923ESA+

MAX923ESA+ Description

The MAX923ESA+ from Analog Devices Inc./Maxim Integrated is a high-performance, dual-channel comparator with an integrated voltage reference, designed for precision applications. Packaged in an 8-SOIC tube, this ROHS3 Compliant and REACH Unaffected device operates over a wide supply range of 2.5V to 11V (single) or ±1.25V to ±5.5V (dual), making it versatile for various circuit configurations. With a CMOS/TTL-compatible output, it delivers a robust 50mA output current, ensuring compatibility with modern digital systems. Its ultra-low quiescent current (7.5µA max) and 12µs propagation delay make it ideal for power-sensitive and time-critical designs.

MAX923ESA+ Features

• High CMRR & PSRR: 80dB common-mode and power supply rejection ratios minimize noise interference.
• Integrated Voltage Reference: Simplifies design by eliminating external reference components.
• Low Input Offset Voltage: 10mV max at 5V ensures accurate comparisons.
• 50mV Hysteresis: Prevents output oscillation in noisy environments.
• Wide Supply Range: Supports single or dual supplies for flexible integration.
