MAX4429ESA+T

Overview

The MAX4429ESA+T is a precision operational amplifier manufactured by Analog Devices Inc./Maxim Integrated. It features a single channel with a gain-bandwidth product of 15 MHz and a slew rate of 7 V/us. The input offset voltage is 50 uV, and the input bias current is 500 fA. Operating on a supply voltage range from 1.7 V to 5.5 V, it consumes 750 uA of quiescent current per channel. The device offers a common-mode rejection ratio of 90 dB and an input voltage noise density of 12.7 nV/sqrt Hz. It supports rail-to-rail output and includes a shutdown function. The component is housed in a WLP-6 package and operates within a temperature range of -40 C to +125 C.

Feature Summary

• Low-offset, low-power design optimized for precision applications
• Rail-to-rail output capability for maximum dynamic range
• Integrated shutdown function for power management
• High common-mode rejection ratio for signal integrity

Applications

• Battery-powered sensor interfaces
• Portable medical instrumentation
• Data acquisition systems
• Active filter circuits

Procurement Notes

Verify the exact ordering suffix and package variant against the official manufacturer datasheet to ensure compatibility with your specific design requirements. Confirm availability status as distribution channels may report limited stock or discontinuation notices. Cross-reference the RoHS compliance details and environmental certifications required for your manufacturing process before finalizing procurement orders.

Selection Notes

Choose this component when low quiescent current and high precision are critical constraints. The wide supply voltage range accommodates single-supply operation down to 1.7 V. Ensure the thermal performance of the WLP-6 package meets your board layout requirements. Compare the input bias current specifications against other low-power amplifiers if ultra-low leakage is necessary for high-impedance sources.
