Analog Devices Inc./Maxim Integrated MAX9052BEUA

Overview

MAX9052BEUA from Analog Devices is a dual comparator with integrated 2.500V precision voltage reference, designed for micropower single-supply operation (2.7V to 5.5V). It delivers rail-to-rail inputs/outputs, 55μA supply current at 2.7V, ±3mV internal hysteresis, and 400ns propagation delay - enabling high-accuracy threshold detection in battery-powered sensor interfaces and portable instrumentation.

For engineers reviewing the MAX9052BEUA datasheet, MAX9052BEUA pinout, MAX9052BEUA application, or MAX9052BEUA equivalent, this page provides verified circuit role, A-grade reference specs (±0.4% initial accuracy, 6ppm/°C tempco), dual-comparator timing behavior, μMAX-8 package layout guidance, and real-world use cases in window comparators and IR receivers.

Technical Context

The MAX9052BEUA integrates two independent comparators sharing one laser-trimmed series-mode voltage reference. Its input stage supports common-mode range from VEE −0.25V to VCC +0.25V with 1.0pA typical bias current and ±0.5mV offset voltage, enabling precise low-level signal discrimination near supply rails.

The output stage features rail-to-rail push-pull drivers capable of sinking/source up to 8mA, while proprietary switching-current limiting minimizes supply glitches - critical for noise-sensitive mixed-signal systems where dynamic power integrity matters more than static quiescent draw.

FAQ

What is the reference voltage accuracy and temperature coefficient of the MAX9052BEUA?

The MAX9052BEUA features a B-grade 2.500V precision reference with ±1% initial accuracy and 100ppm/°C temperature coefficient over −40°C to +85°C. This specification ensures predictable trip-point variation in cost-sensitive applications such as consumer electronics and industrial sensors where extreme stability is not required. The MAX9052BEUA reference remains stable with capacitive loads up to 4.7nF.

Does the MAX9052BEUA support rail-to-rail input and output operation?

Yes, the MAX9052BEUA supports rail-to-rail input operation with a common-mode range extending 0.25V beyond both supply rails (VEE −0.25V to VCC +0.25V), and rail-to-rail push-pull output stages that sink and source up to 8mA. This capability allows the MAX9052BEUA to interface directly with low-voltage sensors and logic families without external level-shifting circuitry.

What is the supply current consumption of the MAX9052BEUA at different operating voltages?

The MAX9052BEUA draws 55μA typical supply current at VCC = 2.7V and 60μA typical at VCC = 5V. These values reflect quiescent operation; dynamic current increases only marginally with output switching frequency due to its patented low-surge output architecture. This makes the MAX9052BEUA especially suitable for always-on battery-powered applications where average current dictates operational lifetime.

Can the MAX9052BEUA be used in window comparator configurations without external components?

Yes, the MAX9052BEUA's dual comparators and integrated 2.500V reference enable standalone window comparator designs. By connecting one comparator's IN+ to the signal and IN− to REF (for upper threshold), and the other's IN− to the signal and IN+ to REF (for lower threshold), the MAX9052BEUA implements full window detection with no external resistors or references - reducing component count and improving accuracy traceability in the MAX9052BEUA-based design.

What package type and pinout does the MAX9052BEUA use, and is it compatible with standard footprints?

The MAX9052BEUA is supplied in an 8-pin μMAX package (3mm × 3mm, 0.8mm height) with exposed thermal pad. Its pinout matches industry-standard SO-8 layouts for mechanical compatibility, though electrical pin assignments differ. Layout requires adherence to Analog Devices' land pattern (Outline No. 21-0036) and thermal pad soldering guidelines to ensure reliability and thermal performance in the MAX9052BEUA implementation.
