MAX9637AXA+T

Instrumentation, Op Amps, Buffer Amps Overview

The MAX9637AXA+T is a dual-channel, single-supply CMOS operational amplifier featuring rail-to-rail input and output capabilities. It operates within a supply voltage range of 2.1V to 5.5V with a typical quiescent current of 36μA per channel. Key electrical parameters include a gain-bandwidth product of 1.5MHz, a slew rate of 0.9V/μs, an input offset voltage maximum of 3.5mV, and an input bias current of ±800pA at the upper temperature limit. The device provides a common-mode rejection ratio of 68dB and an input voltage noise density of 38nV/√Hz. It is housed in an 8-pin SC-70 package and supports an operating temperature range from -40°C to +125°C.

• Ultra-low input bias current enables direct interfacing with high-impedance sensors.
• Wide bandwidth combined with low quiescent current optimizes performance for battery-powered systems.
• High capacitive load drive capability simplifies circuit design without external isolation components.

Instrumentation, Op Amps, Buffer Amps Applications

• Portable medical instruments
• Piezoelectric transducer amplifiers
• Smoke detectors
• Transimpedance amplifiers for photodiodes

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'A' indicates the automotive-grade qualification and '+T' denotes tape-and-reel packaging. Confirm RoHS compliance status as indicated by the '+' symbol. Ensure the selected distributor sources directly from Analog Devices or authorized channels to guarantee authenticity and traceability for the specified temperature range and package type.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when dual-channel signal conditioning is required in space-constrained designs. It is suitable for applications demanding low power consumption alongside wide bandwidth. Consider alternative packages like UTQFN if higher thermal dissipation is needed, or verify that the lack of shutdown control on this specific variant aligns with system power management requirements.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the MAX9636/MAX9637/MAX9638 family of low-power, low-noise op amps. While electrically similar to the MAX9636 (single channel) and MAX9638 (dual channel with shutdown), the MAX9637 specifically offers dual channels in an 8-pin SC-70 package without shutdown functionality. This distinguishes it from the MAX9638AVB+T which includes active-low shutdown pins.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

MAX9638AVB+T requires pin adaptation due to different package and added shutdown pins. MAX9636AXT+T is a single-channel equivalent requiring circuit redesign for dual-channel needs.
