Product details
Overview
The MAX9016AEKA+T from Maxim Integrated is a dual, nanoPower comparator with open-drain output and integrated 1.236V ±1% precision reference, operating from 1.8V to 5.5V supply. It features Beyond-the-Rails™ input range (VEE − 0.2V to VCC + 0.2V), 4mV internal hysteresis, 1.0μA typical supply current at 1.8V, and rail-to-rail output capability up to ±6mA sink/source (via external pull-up). It is designed for ultra-low-power 2-cell battery monitoring in portable medical instruments and telemetry systems.
For engineers reviewing the MAX9016AEKA+T datasheet, MAX9016AEKA+T pinout, MAX9016AEKA+T application, or MAX9016AEKA+T equivalent, this page delivers verified technical context, exact pin functions, real-world use cases in ground-sensing and window detection, and validated alternative options for mixed-voltage system design.
Technical Context
The MAX9016AEKA+T implements a dual-comparator architecture with independent IN+ and IN− inputs per channel and a shared on-chip 1.236V ±1% reference routed to REF/INA− (Pin 2). Its open-drain output stage allows level-shifting beyond VCC-up to 5.5V above VEE-enabling wire-OR logic in multi-supply domains.
Input stage bias current is ±0.15nA (typ) at 25°C, with common-mode range extending 200mV beyond supply rails. The internal 4mV hysteresis band eliminates oscillation during slow signal transitions, while crowbar-current-free switching suppresses supply glitches during output toggling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8V to 5.5V - supports direct operation from single Li-ion or dual alkaline/NiMH cells without regulation. |
| Supply Current | 1.0μA (typ) at 1.8V - enables >1000k-hour operation on 2000mAh AA batteries in continuous monitoring mode. |
| Input Offset Voltage | ≤5mV (max) over −40°C to +85°C - ensures reliable threshold detection across industrial temperature range. |
| Reference Accuracy | 1.236V ±1% (A-grade) - provides stable trip point for precision battery voltage monitoring without external reference. |
| Propagation Delay | 12µs (max) at 1.8V with 100kΩ pull-up - balances speed and power for low-frequency event detection (e.g., low-battery alert). |
| Output Leakage | ≤1µA at VOUT = 5.5V - guarantees high-impedance off-state for accurate bus arbitration in open-drain configurations. |
| Hysteresis | 4mV (internal, fixed) - prevents chatter on noisy sensor inputs such as thermistor or photodiode outputs. |
Pinout & Package
MAX9016AEKA+T is housed in an 8-pin SOT23 package (package code T833+2, outline 21-0078), with exposed pad not connected. Pin 5 and Pin 8 are No Connect (N.C.) and must remain unconnected on PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | REF | 1.236V ±1% precision reference output - sourced from internal bandgap; capable of ±100nA load with <40ppm/°C drift. |
| 2 | REF/INA− | Internally connected reference node and inverting input of Comparator A - enables single-pin threshold configuration for window or overvoltage detection. |
| 3 | INA+ | Noninverting input of Comparator A - accepts signals up to VCC + 0.2V, enabling sensing at supply rail or ground-referenced sources. |
| 4 | VEE | Negative supply terminal - tied to GND in single-supply operation; defines lower bound of input common-mode range. |
| 5, 8 | N.C. | No internal connection - must be left floating; no routing or copper fill required. |
| 6 | OUTA | Open-drain output of Comparator A - requires external pull-up; supports mixed-voltage interfacing up to 5.5V above VEE. |
| 7 | VCC | Positive supply input - powers both comparators and reference; PSRR of 0.1–1mV/V minimizes supply noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Beyond-the-Rails™ Inputs | Accepts signals 200mV below GND or above VCC - enables direct sensing of battery voltage, shunt current, or thermocouple outputs without level-shifting. |
| Open-Drain Output Architecture | Allows wired-AND logic and voltage-level translation - simplifies interface to 3.3V/5V microcontrollers or I²C-compatible buses. |
| Internal 4mV Hysteresis | Eliminates need for external positive feedback resistors - reduces BOM count and layout area in space-constrained wearables and PDAs. |
| Ultra-Low 1.0μA Supply Current | Extends battery life by >2× vs. comparable comparators - critical for maintenance-free telemetry nodes deployed in remote locations. |
| Guaranteed Operation Down to 1.8V | Remains functional through full discharge of 2-cell alkaline/NiMH - avoids premature shutdown in battery management systems. |
Applications
| 2-Cell Battery Monitoring | Ground-Sensing Threshold Detection |
|---|---|
|
Use Scenario: Real-time monitoring of dual alkaline cell voltage (3.0V → 1.8V) in handheld medical instruments to trigger low-battery alerts before system reset. IC Role / Device Role / Timing Role: Dual comparator compares battery voltage against internal 1.236V reference (scaled via resistor divider) to detect under-voltage and over-voltage conditions. Use Value: Eliminates external reference and reduces quiescent current to 1.0μA - extends usable battery life by 280k hours vs. discrete solutions. |
Use Scenario: Detecting zero-crossing or fault conditions in motor driver current-sense shunts referenced to system ground. IC Role / Device Role / Timing Role: Comparator A monitors shunt voltage with IN− tied to GND (VEE) and INA+ sensing shunt top; REF/INA− used as stable 1.236V trip point. Use Value: Beyond-the-Rails™ input allows direct GND-referenced measurement without level-shifter ICs or op-amp buffers. |
| Window Detector for Sensor Outputs | Telemetry System Voltage Supervision |
|
Use Scenario: Validating thermistor or RTD output stays within safe operating range (e.g., 0.8V–2.2V) in environmental monitoring nodes. IC Role / Device Role / Timing Role: Comparator A detects upper threshold (via REF/INA− and INA+), Comparator B detects lower threshold (via separate divider); outputs OR'd externally. Use Value: Single 8-pin SOT23 replaces two discrete comparators + reference - cuts board area by 65% and component count by 3. |
Use Scenario: Ensuring regulated 3.3V supply remains within ±5% tolerance in wireless sensor transmitters powered by energy-harvesting circuits. IC Role / Device Role / Timing Role: Comparator A monitors 3.3V rail using internal reference and resistor divider; open-drain output drives MCU reset pin or RF module enable line. Use Value: 1.0μA supply current prevents parasitic drain on micro-power harvesters - maintains system uptime during low-light or low-vibration conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual nanoPower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9018AEKA+T | Same pinout, same 1.236V ±1% reference, but dual-channel with push-pull output (not open-drain) | Requires no external pull-up; unsuitable for wired-AND or level-shifting; higher output drive (±6mA) | Select when driving CMOS inputs directly or needing faster rise time without pull-up resistor. |
| TLV3692IDR | Single 1.8V nanoPower comparator (no internal reference), 350nA supply current, SC70-6 package | Requires external reference; lower current but only one channel; smaller footprint but no integrated reference | Select when ultra-low current (<0.4μA) is critical and reference can be shared across multiple channels. |
Compared with MAX9016AEKA+T, MAX9018AEKA+T offers push-pull output for simpler interfacing but forfeits level-shifting flexibility, while TLV3692IDR reduces current by 65% yet increases BOM complexity and board area due to external reference and dual-part requirement for dual-channel function.

FAQ
What is the reference voltage accuracy and temperature stability of the MAX9016AEKA+T?
The MAX9016AEKA+T features an A-grade internal reference of 1.236V ±1% at +25°C, with total accuracy of ±2.5% over −40°C to +85°C. Its temperature coefficient is 40ppm/°C, and reference voltage variation versus supply voltage is ≤0.5mV/V - ensuring stable trip points across battery discharge and thermal cycling in portable devices.
Can the MAX9016AEKA+T operate from a single 1.8V supply?
Yes, the MAX9016AEKA+T is fully specified down to 1.8V supply voltage. At 1.8V, it draws 1.0μA (typ), maintains 4mV hysteresis, and sustains valid input common-mode range from −0.2V to +2.0V - making it ideal for direct connection to deeply discharged 2-cell alkaline or NiMH batteries.
What is the maximum sink current capability of the MAX9016AEKA+T open-drain output?
The MAX9016AEKA+T open-drain output (OUTA, Pin 6) can sink up to 6mA while maintaining VOL ≤300mV at 1.8V supply and 25°C. This allows direct driving of LEDs, MOSFET gates, or microcontroller interrupt pins without external buffer stages - provided the external pull-up resistor is sized accordingly.
How does the Beyond-the-Rails™ input feature benefit ground-referenced sensing?
The MAX9016AEKA+T accepts inputs as low as VEE − 0.2V (i.e., −0.2V when VEE = GND), enabling direct connection to current-sense shunts or thermocouples referenced to ground. This eliminates level-shifting circuitry, reduces offset errors, and preserves signal integrity in low-voltage, high-precision measurement paths.
Is the MAX9016AEKA+T pin-compatible with other devices in the MAX9015–MAX9020 family?
Yes, the MAX9016AEKA+T shares identical 8-pin SOT23 pinout with MAX9015AEKA+T, MAX9017AEKA+T, MAX9018AEKA+T, MAX9019AEKA+T, and MAX9020AEKA+T. However, internal functionality differs: MAX9016AEKA+T has open-drain output and REF/INA−, whereas MAX9015AEKA+T uses push-pull output and separate REF and IN− pins.
