Product details
Overview
The MAX9061EBS+TG45 from Analog Devices is a nanoPower single comparator with inverting input configuration, open-drain output, and external reference voltage interface (0.9V–5.5V). It draws only 100nA max supply current, operates from –40°C to +85°C, and uses a 4-bump UCSP package (1mm × 1mm × 0.6mm) for ultra-compact battery-powered signal threshold detection in portable medical devices and wearables.
For engineers reviewing the MAX9061EBS+TG45 datasheet, MAX9061EBS+TG45 pinout, MAX9061EBS+TG45 application, or MAX9061EBS+TG45 equivalent, key selection criteria include its inverting-input topology, 100nA quiescent current, –0.3V to +5.5V input voltage range independent of supply, and compatibility with low-voltage microcontroller I/O domains down to 0.9V.
Technical Context
The MAX9061EBS+TG45 implements an inverting-input comparator architecture with high-impedance inputs that remain functional even when VREF = 0V-enabling robust power-gating schemes in energy-harvesting and wake-on-event systems. Its input stage avoids ESD diode clamping to VREF, allowing VIN to exceed VREF by up to 0.3V beyond absolute maximum ratings without damage.
It features internal hysteresis (±12mV typical) for noise immunity and supports adaptive thresholding via externally variable VREF (0.9V–5.5V), making it suitable for dynamic signal-level detection in sensor front-ends where DAC-driven reference adjustment is required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 100nA max - enables multi-year operation on coin-cell batteries in always-on monitoring circuits. |
| Input Voltage Range | –0.3V to +5.5V - supports rail-to-rail sensing across mixed-supply systems without level-shifting. |
| Reference Voltage Range | 0.9V to 5.5V - allows direct interfacing with DAC outputs or low-dropout LDOs for programmable trip points. |
| Propagation Delay | 15μs at ±100mV overdrive - sufficient for slow-varying biosignals (ECG, temperature) while minimizing power. |
| Input Offset Voltage | 1.3mV (typ), 6mV (max) - ensures accurate threshold detection in precision analog sensor interfaces. |
| Operating Temperature | –40°C to +85°C - qualified for industrial and portable medical environments without derating. |

Pinout & Package
MAX9061EBS+TG45 uses a 4-bump UCSP (Ultra Compact Silicon Package) with 0.5mm bump pitch, 1mm × 1mm footprint, and 0.6mm height. The G45 suffix denotes protective die coating for enhanced moisture and mechanical robustness in handheld assemblies.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | OUT | Open-drain output requiring external pull-up; compatible with logic supplies up to 5.5V independent of VREF. |
| A2 | IN | Inverting input - output goes low when IN exceeds VREF; supports direct connection to resistive divider or sensor output. |
| B1 | REF | External reference input and power supply pin; must be bypassed with 0.1µF capacitor to GND for stable operation. |
| B2 | GND | Analog ground return; shared reference for input, output, and internal circuitry - requires low-impedance connection to system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Inverting-input topology | Enables direct use in active-low trigger configurations (e.g., battery undervoltage alert) without external inversion logic. |
| 0.9V–5.5V VREF interface | Permits dynamic threshold programming via DAC or potentiometer, supporting adaptive sensor calibration in field-deployed devices. |
| 100nA max supply current | Reduces average power to <100nW at 1V - ideal for energy-harvesting nodes where every nanoamp impacts runtime. |
| VIN > VREF immunity | Allows input signals to exceed VREF by up to 0.3V beyond absolute max rating without latch-up or damage, simplifying ESD protection design. |
| Internal hysteresis (±12mV) | Eliminates need for external feedback resistors in noisy environments like motor-driven portable equipment or RF-dense IoT enclosures. |
Applications
| Low-Power Battery Monitoring | Wearable Sensor Threshold Detection |
|---|---|
Use Scenario: Monitoring Li-ion cell voltage during deep-sleep mode in smart watches to trigger wake-up at 3.0V cutoff. IC Role / Device Role / Timing Role: Inverting comparator compares cell voltage against DAC-set reference; asserts low on undervoltage event.

IC Role / Device Role / Timing Role: NanoPower comparator monitors analog gas sensor output and triggers MCU only upon valid threshold crossing. Use Value: 1mm × 1mm UCSP footprint minimizes PCB area on small solar harvester boards; G45 coating resists humidity-induced leakage drift. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7011DBVR | Push-pull output; 650nA max supply current; fixed 1.24V internal reference; no external REF support. | Requires external resistor divider for adjustable thresholds; less suitable for DAC-driven adaptive detection. | Select when push-pull output eliminates need for pull-up and fixed reference suffices. |
| MAX40005YBET+ | Open-drain output; 300nA max supply current; 0.4V internal reference; 5-pin SOT23 package (larger footprint). | Higher current draw reduces battery lifetime; larger package limits use in ultra-compact designs. | Select when UCSP assembly capability is unavailable and 300nA is acceptable for target runtime. |
Compared with TLV7011DBVR and MAX40005YBET+, the MAX9061EBS+TG45 uniquely combines inverting-input topology, 100nA max current, and full 0.9V–5.5V external reference support in a 1mm² package-making it optimal for space- and power-constrained adaptive thresholding where precise, software-tunable trip points are required.

FAQ
What is the function of the REF pin on the MAX9061EBS+TG45?
The REF pin on the MAX9061EBS+TG45 serves as both the external reference voltage input and the primary power supply for the device. It accepts 0.9V to 5.5V and must be bypassed with a 0.1µF capacitor to GND. Unlike conventional comparators, the MAX9061EBS+TG45 draws its operating current directly from this pin, eliminating the need for a separate VCC rail and simplifying power architecture in single-supply systems.
Does the MAX9061EBS+TG45 support inverting or noninverting input configuration?
The MAX9061EBS+TG45 is configured as an inverting-input comparator: the output goes low when the voltage at the IN pin exceeds the voltage applied to the REF pin. This is confirmed in the Pin/Bump Description table and Typical Operating Circuits section of the datasheet. Noninverting variants in the same family include MAX9060, MAX9062, and MAX9064.
Can the MAX9061EBS+TG45 operate with a supply voltage below 1.0V?
No-the MAX9061EBS+TG45 requires a minimum REF voltage of 0.9V per the Electrical Characteristics table, and its guaranteed operation begins at 0.9V. While some test data show functionality down to ~0.85V, the datasheet specifies 0.9V as the lower limit for production-tested performance across temperature. For sub-0.9V operation, alternative comparators such as the MAX40005 (0.4V reference) or TLV7031 (0.9V min) should be evaluated.
What is the purpose of the G45 suffix in MAX9061EBS+TG45?
How does the MAX9061EBS+TG45 handle input voltages exceeding the REF voltage?
The MAX9061EBS+TG45 features an input stage architecture that avoids traditional ESD diode clamping between IN and REF, allowing the input voltage to safely exceed REF by up to 0.3V beyond the Absolute Maximum Rating of +6V (i.e., up to +6.3V) without damage or latch-up. This enables direct interfacing with higher-voltage sensor outputs or legacy analog signals without external attenuation or level-shifting circuitry.
