MAX44260AYT+T

Instrumentation, Op Amps, Buffer Amps Overview

The MAX44260AYT+T is a single-channel, low-offset, low-power operational amplifier featuring rail-to-rail input and output capabilities. It operates within a supply voltage range of 1.8V to 5.5V (or 1.7V at 0°C to +70°C) and supports an operating temperature range from -40°C to +125°C. The device incorporates a fast-power-on shutdown mode that reduces quiescent current to less than 1µA with a recovery time under 30µs. Key electrical specifications include a unity-gain bandwidth of 15MHz, a slew rate of 7V/µs, and a maximum input offset voltage of 500µV across the full temperature range. It utilizes a unique input stage architecture with an integrated charge pump to eliminate crossover distortion.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific package suffix 'YT' corresponds to the Thin µDFN (Ultra-Thin LGA) configuration when sourcing components. Confirm RoHS compliance status via official manufacturer documentation or authorized distributor declarations prior to procurement. Ensure the ordering part number matches the required pinout and thermal characteristics for the intended PCB layout.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for designs requiring high precision combined with low power consumption in space-constrained environments. The inclusion of a dedicated shutdown pin makes it suitable for battery-powered systems requiring extended standby modes. Consider the 1mm x 1.5mm footprint when evaluating board real estate against other family members like the SC70 variant.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the MAX44259/MAX44260/MAX44261/MAX44263 family of 1.8V, 15MHz low-offset, low-power, rail-to-rail I/O op amps. While sharing core performance metrics such as bandwidth and noise density, the MAX44260AYT+T is distinguished by its specific 6-pin Thin µDFN packaging and the integration of a shutdown control feature not present in all family variants.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The MAX44260AXT+ serves as a direct functional substitute utilizing the same electrical specifications but housed in a 6-pin SC70 package instead of the Thin µDFN format. Designers must verify mechanical footprint compatibility and thermal dissipation requirements when swapping between these package types.

Instrumentation, Op Amps, Buffer Amps FAQ

How does the MAX44260 handle crossover distortion?

It employs a unique input stage architecture powered by an integrated, ultra-quiet charge pump that creates an internal voltage rail above VDD. This design eliminates the crossover distortion typically found in standard CMOS input structures.

What is the behavior of the device upon exiting shutdown mode?

Upon exiting shutdown mode, the device recovers in under 30µs. It retains its power-up trim settings and does not perform a new self-calibration sequence during this transition.
