MAX9916EKA+T

Instrumentation, Op Amps, Buffer Amps Overview

The MAX9916EKA+T is a dual-channel CMOS operational amplifier from the MAX9914–MAX9917 family, designed for battery-powered applications. It features a 1MHz gain-bandwidth product and operates on a single supply voltage ranging from 1.8V to 5.5V. The device consumes a typical supply current of 40µA at 5.5V and offers rail-to-rail input and output capabilities. Key electrical specifications include an ultra-low input bias current of 1pA, an input offset voltage of ±1mV, and a common-mode rejection ratio of 70dB. It is housed in an 8-pin SOT23 package and supports an operating temperature range of -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the component matches the specific Analog Devices/Maxim Integrated part number MAX9916EKA+T. Confirm the package type is 8-pin SOT23 and that the suffix indicates lead-free/RoHS compliance. Ensure the ordering code includes the 'T' designation if tape-and-reel packaging is required for automated assembly processes.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when low quiescent current and wide input/output voltage swing are critical. The dual-channel configuration allows for compact designs in space-constrained portable devices. Verify that the 1MHz bandwidth meets the signal frequency requirements and that the 40µA supply current aligns with the system's power budget constraints.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the MAX9914–MAX9917 series of micro-power operational amplifiers. While the MAX9914 and MAX9915 are single-channel units, the MAX9916 provides two channels in a compact footprint. Unlike the MAX9917, this specific model does not include a shutdown pin, maintaining continuous operation throughout its active lifecycle.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The MAX9916EKA-T serves as the non-RoHS compliant alternative within the same series.
