Product details
Overview
MAX9075EXK-T from Maxim Integrated is a single, rail-to-rail input/output comparator optimized for ultra-low-power, single-supply portable systems. It delivers 580ns propagation delay at just 3µA supply current, operates from 2.1V to 5.5V, features ground-sensing inputs (–0.2V to VCC – 1.2V), and drives 2mA loads with push-pull output - ideal for battery-powered threshold detection in compact IR receivers.
For engineers reviewing the MAX9075EXK-T datasheet, MAX9075EXK-T pinout, MAX9075EXK-T application, or MAX9075EXK-T equivalent, this page provides verified technical context, package-specific pin mapping, real-world use cases, and validated alternative comparators for low-voltage, sub-4µA portable designs.
Technical Context
The MAX9075EXK-T uses BiCMOS process technology to achieve stable 3µA quiescent current across –40°C to +85°C while maintaining 580ns propagation delay (typical) under 100mV overdrive. Its input stage lacks differential clamping, enabling rail-to-rail differential input voltage tolerance and no phase inversion during overdrive.
Output stage employs large internal push-pull drivers delivering rail-to-rail swing into 2mA loads, with VOL ≤ 0.4V and VOH ≥ VCC – 0.4V at 2mA. Input offset voltage is ±1mV (max), CMRR is 60dB (min), and PSRR is 54dB (min) - all specified over full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 3µA per comparator - enables multi-year operation on coin-cell batteries in always-on sensing nodes. |
| Propagation Delay | 580ns (typ) - supports fast edge detection in digital line receivers and keyless entry wake-up circuits. |
| Supply Voltage Range | 2.1V to 5.5V - compatible with Li-ion, Li-Po, and dual-AA systems without LDO pre-regulation. |
| Input Common-Mode Range | –0.2V to VCC – 1.2V - allows direct ground-referenced signal monitoring (e.g., battery voltage below GND). |
| Output Drive Capability | Rail-to-rail swing into 2mA load - directly interfaces TTL/CMOS logic without pull-up resistors. |
| Input Offset Voltage | ±1mV (max) - ensures accurate 10mV-level threshold discrimination in precision sensor interfaces. |
| Input Bias Current | –5nA (typ) - minimizes error in high-impedance reference divider networks (e.g., >1MΩ). |
Pinout & Package
The MAX9075EXK-T is packaged in a 5-pin SC70 (X5+1 outline), measuring 2.0mm × 1.25mm × 0.9mm - one of the smallest surface-mount packages for single comparators.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for all internal circuitry and output stage return path. |
| 2 | IN– | Inverting input - accepts signals down to –0.2V; no internal clamp to IN+. |
| 3 | IN+ | Noninverting input - supports common-mode range extending to VCC – 1.2V. |
| 4 | VCC | Positive supply terminal - powers internal biasing and output stage; max 6V absolute rating. |
| 5 | OUT | Push-pull output - actively drives high/low; sinks/source up to 2mA; no external pull-up required. |
Key Features
| Feature | Design Value |
|---|---|
| No output phase inversion on overdriven inputs | Enables reliable decision-making in noisy environments where input transients exceed common-mode limits. |
| Rail-to-rail output swing into 2mA | Eliminates need for external level-shifting or pull-up components in mixed-voltage logic interfaces. |
| Ground-sensing input capability | Supports direct connection to sensors with outputs referenced below GND (e.g., current-sense amplifiers). |
| No differential input clamp | Permits unrestricted differential voltage swing (e.g., ±5V across inputs) without damage or latch-up. |
| Ultra-low 3µA supply current | Reduces average power to <15µW at 5V - critical for energy harvesting and long-life IoT endpoints. |
Applications
| Battery Voltage Monitor | IR Remote Signal Decoder |
|---|---|
|
Use Scenario: Detecting low-battery condition in wearable health monitors using a resistive divider off a 3.0V Li-Po cell. IC Role / Device Role / Timing Role: Single comparator comparing divided battery voltage against 1.2V reference to assert low-battery flag. Use Value: 3µA quiescent current extends system standby life by >2× versus 10µA alternatives; ground-sensing input accommodates divider tied to battery negative. |
Use Scenario: Converting modulated 38kHz IR carrier bursts into clean digital pulses for microcontroller decoding. IC Role / Device Role / Timing Role: High-speed comparator with 580ns delay converting analog IR photodiode output to TTL-compatible logic edges. Use Value: Fast propagation delay preserves pulse timing integrity; rail-to-rail output ensures full logic swing into MCU GPIO with no external components. |
| Keyless Entry RF Wake-Up | Digital Line Receiver |
|
Use Scenario: Detecting valid 125kHz LF preamble in automotive key fob receivers to wake main MCU from deep sleep. IC Role / Device Role / Timing Role: Low-power comparator triggering interrupt on envelope-detected LF burst edge. Use Value: Sub-4µA supply current enables continuous listen mode for months on CR2032; no phase inversion prevents false wake-ups during signal overshoot. |
Use Scenario: Receiving RS-232 or proprietary UART-like signals in industrial control panels with wide common-mode noise. IC Role / Device Role / Timing Role: Threshold detector rejecting common-mode noise while preserving data edges for UART sampling. Use Value: 60dB CMRR suppresses >1Vpp noise on shared PCB traces; –0.2V to VCC–1.2V input range captures degraded signal levels near rails. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3691IDCKR | 2.5µA supply current, 1.8V–5.5V operation, but only 1.2V common-mode lower limit (not ground-sensing); 850ns delay. | Lacks true ground-sensing - unsuitable for sub-GND referenced inputs; slower response limits IR receiver use. | Select when lowest possible current is primary and input stays ≥0V; verify input range compatibility. |
| LMV7215M5X | 650ns delay, 12µA supply current, rail-to-rail input/output, but no guaranteed operation below 2.7V. | Higher current reduces battery life; 2.7V min supply excludes 2xAA or LiFePO₄ systems. | Choose for higher drive strength (5mA) where supply >2.7V is assured and 3µA is not critical. |
Compared with TLV3691IDCKR and LMV7215M5X, the MAX9075EXK-T uniquely combines ground-sensing input, 580ns speed, and 3µA consumption - making it the only option qualified for sub-2.7V, ground-referenced, battery-critical portable detection.

FAQ
What is the operating temperature range for the MAX9075EXK-T?
The MAX9075EXK-T is rated for –40°C to +85°C operation, fully specified across this range for parameters including supply current, propagation delay, input offset voltage, and common-mode rejection ratio. This makes the MAX9075EXK-T suitable for automotive cabin modules, outdoor wearables, and industrial handheld devices where ambient temperature swings are expected.
Does the MAX9075EXK-T require external pull-up resistors on its output?
No, the MAX9075EXK-T features a push-pull output stage capable of actively driving both high and low states into loads up to 2mA. Because the MAX9075EXK-T output can source and sink current without external components, pull-up resistors are unnecessary - simplifying PCB layout and reducing BOM count in space-constrained designs.
Can the MAX9075EXK-T accept input voltages below ground?
Yes, the MAX9075EXK-T supports a common-mode input range extending to –0.2V, enabling true ground-sensing operation. This means the MAX9075EXK-T can reliably compare signals referenced slightly below GND - such as current-sense amplifier outputs or thermocouple interfaces - without damage or performance degradation.
What is the maximum load the MAX9075EXK-T output can drive while maintaining rail-to-rail swing?
The MAX9075EXK-T maintains rail-to-rail output swing with loads up to 2mA, as confirmed by VOL ≤ 0.4V and VOH ≥ VCC – 0.4V specifications at that current. Driving heavier loads will compress the output swing; therefore, the MAX9075EXK-T is optimized for direct interfacing with standard TTL/CMOS logic inputs and low-power microcontroller GPIOs.
Is the MAX9075EXK-T RoHS-compliant and lead-free?
Yes, the MAX9075EXK-T carries the "+" suffix indicating a lead(Pb)-free and RoHS-compliant SC70 package. The device meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) and is qualified for reflow soldering at up to +260°C peak temperature - consistent with modern lead-free assembly requirements.
