MAX917ESA

MAX917ESA Description

The MAX917ESA from Analog Devices Inc./Maxim Integrated is a low-power, high-precision comparator with an integrated voltage reference, designed for applications requiring ultra-low quiescent current and stable performance. Packaged in an 8-SOIC tube, this obsolete but REACH-compliant device operates over a 1.8V to 5.5V supply range, making it suitable for battery-powered and portable electronics. With a 1.6µA max quiescent current and 50mA output drive capability, it balances efficiency with robust performance. The comparator features 4mV hysteresis for noise immunity and a 95µs max propagation delay, ensuring reliable switching in critical timing applications.

MAX917ESA Features

• Ultra-Low Power: Quiescent current as low as 1.6µA extends battery life in portable devices.
• High Precision: 5mV max input offset voltage and 80dB PSRR ensure accuracy in noisy environments.
• Integrated Voltage Reference: Simplifies design by eliminating external reference components.
• Wide Supply Range: Operates from 1.8V to 5.5V, compatible with Li-ion and single-cell battery systems.
• Robust Output: 50mA sink/source current drives relays, LEDs, or other loads directly.
• Noise Immunity: 4mV hysteresis prevents false triggering in fluctuating signal conditions.

MAX917ESA Applications

• Battery-Powered Systems: Ideal for energy-efficient designs like IoT sensors and wearables.
• Threshold Detection: Used in overvoltage/undervoltage monitoring circuits.
• Portable Medical Devices: Leverages low power and precision for glucose meters or pulse oximeters.
• Industrial Control: Reliable switching in motor control or power management systems.
• Consumer Electronics: Enables compact, low-power designs in smart home devices.

Conclusion of MAX917ESA

The MAX917ESA stands out for its ultra-low power consumption, integrated reference, and high noise immunity, making it a versatile choice for precision-critical, battery-operated applications. While obsolete, its ROHS3 compliance and REACH-unaffected status ensure suitability for legacy designs. Engineers seeking a balance of efficiency, accuracy, and compactness will find this comparator a compelling solution for low-voltage systems.
