Product details
Overview
MAX40005ANS02+ from Analog Devices is a nanoPower, inverting-input, push-pull-output comparator with factory-trimmed 0.2V internal reference, 500nA supply current, 0.1V–5.5V input voltage range, and operation from 1.7V to 5.5V supply - deployed in ultra-compact 0.73mm × 0.73mm 4-bump WLP for battery-critical portable medical sensors and low-voltage IoT wake-up circuits.
For engineers reviewing the MAX40005ANS02+ datasheet, MAX40005ANS02+ pinout, MAX40005ANS02+ application, or MAX40005ANS02+ equivalent, key selection considerations include its inverting logic polarity, 0.2V precision internal reference (±12mV at +25°C), push-pull output eliminating external pull-up, -40°C to +125°C automotive qualification, and WLP thermal performance (θJA = 104.4°C/W).
Technical Context
The MAX40005ANS02+ implements an inverting-input comparator architecture with integrated 0.2V temperature-compensated reference, enabling direct threshold detection without external components. Its input stage maintains high impedance even at VCC = 0V, supporting power-gating schemes in energy-harvesting systems.
It features 8mV typical internal hysteresis for noise immunity, 9µs propagation delay (100mV overdrive), and rail-to-rail input capability exceeding VCC by up to 0.3V beyond absolute max ratings - enabled by ESD-diode-free input design and on-chip RF filtering.
Key Specifications

FAQ
What is the internal reference voltage tolerance of MAX40005ANS02+ over temperature?
The MAX40005ANS02+ features a factory-trimmed 0.2V internal reference with ±12mV tolerance at +25°C, widening to ±26mV over the full -40°C to +125°C operating range. This specification is guaranteed per the Electrical Characteristics table on page 4 of the datasheet and reflects total error including initial trim, drift, and hysteresis - enabling reliable low-threshold detection in automotive and medical environments without external calibration.
Does MAX40005ANS02+ require an external pull-up resistor on its output?
No, MAX40005ANS02+ does not require an external pull-up resistor because it features a push-pull output stage capable of both sourcing and sinking current. This eliminates the need for external passive components, reduces BOM count, and ensures clean logic transitions across its full 1.7V–5.5V supply range - unlike open-drain variants such as MAX40003ANS02+ which mandate external pull-up networks.
Can MAX40005ANS02+ operate with input voltages below its supply voltage?
Yes, MAX40005ANS02+ supports input voltages as low as 0.1V regardless of supply voltage - a key feature for detecting sub-1V signals like thermistor outputs or battery cell voltages. Its rail-to-rail input architecture and ESD-diode-free design allow operation down to 0.1V while maintaining high input impedance, even when VCC is powered down to 0V.
What is the thermal resistance (θJA) of the MAX40005ANS02+ WLP package?
The MAX40005ANS02+ in its 4-bump WLP package has a junction-to-ambient thermal resistance (θJA) of 104.4°C/W, measured per JEDEC JESD51-7 on a four-layer board. This value is significantly lower than the 255.9°C/W of the SOT23 variant (MAX40015ANS02+), making the WLP version better suited for thermally constrained applications such as sealed wearable enclosures or high-density sensor modules.
How does the internal hysteresis of MAX40005ANS02+ improve system reliability?
The MAX40005ANS02+ integrates 8mV typical internal hysteresis to prevent multiple output toggles caused by noise or slow-moving input signals near the 0.2V threshold. This eliminates the need for external positive feedback networks - especially valuable in space-constrained designs - and ensures glitch-free wake-up events in battery-powered sensors, thereby improving system-level power efficiency and measurement integrity.
