Product details
Overview
MAX9060EUK+T from Analog Devices is an ultra-small, nanoPower single comparator with open-drain output, designed for space- and power-constrained portable electronics. It features 100nA max quiescent current, -0.3V to +5.5V input voltage range independent of supply, and operates from 0.9V to 5.5V external reference voltage across -40°C to +85°C. Used in cell phone battery monitoring and low-voltage microcontroller wake-up circuits.
For engineers reviewing the MAX9060EUK+T datasheet, MAX9060EUK+T pinout, MAX9060EUK+T application, or MAX9060EUK+T equivalent, this page delivers verified electrical behavior, package-specific terminal mapping, real-world timing performance (15µs propagation delay), and validated alternatives for low-power signal threshold detection in battery-operated systems.
Technical Context
The MAX9060EUK+T implements a BiCMOS input stage enabling rail-to-rail input operation beyond VREF (up to -0.3V to +5.5V) while maintaining high impedance even when powered down (VREF = 0V). Its open-drain output requires an external pull-up and supports level-shifting between disparate logic domains.
It draws supply current solely from the VREF pin (not VCC), enabling operation with no dedicated power rail-ideal for systems where only a reference or I/O voltage is available. Internal hysteresis (±12mV) ensures noise immunity without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 100nA max - enables >10-year battery life in coin-cell-powered sensors |
| Input Voltage Range | -0.3V to +5.5V - accepts signals below ground or above supply without clamping diodes |
| Propagation Delay | 15µs at ±100mV overdrive - supports fast wake-up response in low-power sleep modes |
| Input Offset Voltage | 6mV typical - ensures accurate threshold detection near 0.2V–1.8V reference levels |
| Hysteresis | ±12mV - suppresses false triggering from EMI or slow-rising input edges |
| Reference Input Range | 0.9V to 5.5V - compatible with common MCU I/O voltages (1.8V, 3.3V, 5V) |
| Operating Temperature | -40°C to +85°C - qualified for industrial and consumer portable environments |
Pinout & Package
MAX9060EUK+T is housed in a RoHS-compliant 5-pin SOT23 package (outline 21-0057), footprint-compatible with standard SOT23-5 land patterns and measuring 2.9mm × 1.6mm × 1.1mm.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | REF | Reference input and primary power source - supplies internal circuitry; must be bypassed with 0.1µF capacitor to GND |
| 2 | GND | Analog ground return - shared reference for REF, IN, and OUT; requires low-impedance connection |
| 3 | GND | Second ground pin - reduces package inductance and improves RF immunity in noisy layouts |
| 4 | IN | Noninverting input - compares applied signal against REF; supports inputs down to -0.3V |
| 5 | OUT | Open-drain output - sinks current only; requires external pull-up to define logic-high level and interface voltage |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low supply current | 100nA max enables multi-year operation on CR2032 batteries in always-on sensing nodes |
| Input beyond supply capability | Accepts VIN down to -0.3V or up to +5.5V regardless of REF voltage - eliminates need for level-shifting front-end |
| Powered-down input protection | Maintains high-Z input state when REF = 0V - prevents back-driving or leakage into unpowered systems |
| Integrated RF filtering | On-chip filtering rejects GSM/ISM-band interference without external ferrites or RC networks |
| Internal hysteresis | ±12mV built-in hysteresis eliminates external feedback components for stable switching in noisy environments |
Applications
| Cell Phone Battery Monitoring | Portable Medical Sensor Wake-Up |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3691IDBVR | 250nA max supply current; 1.8V to 5.5V supply range; no REF pin - powered from VCC only | Requires dedicated VCC rail; lacks REF-based flexibility for DAC-driven thresholds | Select when system has stable 1.8V+ supply and no adaptive reference needed |
| MAX40005XK+T | 300nA max supply current; integrated 1.2V reference; push-pull output; 4-bump WLP only | No external REF control; fixed internal reference limits threshold adjustability | Select when board space is critical and fixed 1.2V threshold suffices |
Compared with TLV3691IDBVR and MAX40005XK+T, the MAX9060EUK+T uniquely supports ultra-low-current operation *with* user-defined reference voltage (0.9V–5.5V), enabling precise, software-adjustable thresholds in single-supply, battery-limited systems where power rail availability is constrained.

FAQ
What is the maximum input voltage the MAX9060EUK+T can tolerate?
The MAX9060EUK+T supports an input voltage range of -0.3V to +5.5V, independent of the REF voltage level. This allows direct connection to signals exceeding the reference or even going slightly negative - critical for interfacing with sensors or legacy analog outputs without level-shifting circuitry. Absolute maximum rating extends to +6V, but sustained operation above +5.5V is not recommended.
Does the MAX9060EUK+T require a separate VCC supply?
No. The MAX9060EUK+T draws all operating current from the REF pin - there is no VCC pin. REF serves both as the reference voltage input and the sole power source. This architecture eliminates the need for a dedicated supply rail and enables operation in systems where only a reference or I/O voltage (e.g., 1.8V or 3.3V from an MCU) is available.
Can the MAX9060EUK+T drive a microcontroller GPIO directly?
Yes - when used with an appropriate external pull-up resistor (e.g., 10kΩ to 3.3V), the open-drain output of the MAX9060EUK+T interfaces cleanly with standard CMOS GPIO inputs. The VOL specification (0.20V max at 25µA sink) ensures reliable logic-low recognition, and the high-impedance OFF state avoids contention during MCU reset or sleep states.
How does the MAX9060EUK+T behave when REF is set to 0V?
When REF = 0V, the MAX9060EUK+T enters a powered-down state: input bias current drops to <0.1nA, inputs remain high-impedance, and the output floats in high-Z state. This feature enables safe "hot insertion" into live systems and eliminates back-current paths - essential for modular or field-replaceable battery-powered subsystems.
Is the MAX9060EUK+T pin-compatible with other devices in the MAX9060–MAX9064 family?
Yes - all SOT23-packaged variants (MAX9060EUK+, MAX9061EUK+, MAX9062EUK+, MAX9063EUK+, MAX9064EUK+) share identical 5-pin SOT23 pinouts and footprints. However, functionality differs: MAX9060/MAX9061 use external REF and open-drain outputs; MAX9062/MAX9063 include internal 0.2V reference and open-drain outputs; MAX9064 adds push-pull output. Electrical substitution requires validation of reference architecture and output type.
