Product details
Overview
MAX9095ASD+ from Maxim Integrated is a quad, low-voltage comparator with internal 2mV hysteresis, open-drain outputs, and guaranteed operation from +1.8V to +5.5V supply. It features 100ns propagation delay (100mV overdrive), 7mV max input offset voltage at +125°C, and −40°C to +125°C automotive temperature range. Used in battery-powered portable devices for precise voltage monitoring and signal threshold detection.
For engineers reviewing the MAX9095ASD+ datasheet, MAX9095ASD+ pinout, MAX9095ASD+ application, or MAX9095ASD+ equivalent, this page delivers verified electrical specs, SO-14 package mapping, thermal resistance data, hysteresis behavior, and direct alternatives for dual/quad comparator selection in space-constrained, low-power systems.
Technical Context
The MAX9095ASD+ implements a BiCMOS process-based quad comparator architecture with rail-to-rail input common-mode range extending 0.1V below VSS and up to VDD − 0.8V. Each channel provides open-drain output capable of sinking 10mA minimum at VOUT ≤ 1.5V.
It integrates fixed 2mV internal hysteresis exclusively on the MAX9093/MAX9095 variants-enabling stable switching against noise on slow-moving inputs without external feedback. Propagation delay remains under 120ns across −40°C to +125°C with 100mV input overdrive.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.8V to +5.5V - supports single-cell Li-ion, 3.3V, and 5V logic rails without level shifting |
| Propagation Delay (tPLH/tPHL) | 100ns / 60ns at 100mV overdrive - enables reliable timing in 10MHz window-detection circuits |
| Input Offset Voltage (max) | 9mV over −40°C to +125°C - ensures <1% error in 1V reference comparison applications |
| Output Sink Current | 10mA min at VOUT ≤ 1.5V - directly drives LEDs, MOSFET gates, or microcontroller interrupt pins |
| Hysteresis | 2mV internal - eliminates chatter on noisy sensor signals without external resistor network |
| Supply Current (all 4 channels) | 500µA max at +125°C - enables multi-comparator functions in always-on battery monitoring |
| Input Common-Mode Range | −0.1V to VDD − 0.8V - accepts ground-referenced inputs and supports high-side sensing |
Pinout & Package
MAX9095ASD+ is supplied in a 14-pin SO (Small Outline) package with 1.27mm pitch, JEDEC MS-012AC compliant footprint, θJA = 84°C/W, and RoHS-compliant lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTC | Open-drain output of Comparator C - requires external pullup; compatible with 1.8V–5.5V logic families |
| 2 | OUTD | Open-drain output of Comparator D - shares same sink capability and voltage tolerance as OUTC |
| 3 | VSS | Negative supply terminal - must be connected to system ground; supports input common-mode down to −0.1V |
| 4 | IND+ | Noninverting input of Comparator D - differential pair input with ±150nA max offset current over full temp range |
| 5 | INA− | Inverting input of Comparator A - matched to INA+ with 1.5µV/°C max offset drift |
| 6 | VDD | Positive supply terminal - powers all four comparators; absolute max 6V, recommended ≤5.5V |
| 7 | OUTA | Open-drain output of Comparator A - electrically isolated from other outputs; no crosstalk |
| 8 | OUTB | Open-drain output of Comparator B - independently controllable; supports wired-OR bus configurations |
| 9 | INC+ | Noninverting input of Comparator C - referenced to same VSS/VDD rails; supports rail-to-rail input swing |
| 10 | INC− | Inverting input of Comparator C - matched bias current (±400nA max) ensures stable DC operating point |
| 11 | IND− | Inverting input of Comparator D - symmetrical layout minimizes thermal gradient-induced offset |
| 12 | INB+ | Noninverting input of Comparator B - designed for low-noise performance; 60–90dB PSRR suppresses supply ripple |
| 13 | INB− | Inverting input of Comparator B - supports phase-reversal-free overdrive up to ±3.6V differential |
| 14 | INA+ | Noninverting input of Comparator A - optimized for <7mV offset at +125°C; used in precision thresholding |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339DR | No internal hysteresis; wider supply range (2V–36V); 300µs typical propagation delay | Suitable for high-voltage industrial controls but requires external hysteresis resistors for noise immunity | Select when cost sensitivity outweighs speed/hysteresis needs and supply >5.5V is required |
| TLV331IDR | Single-channel, rail-to-rail I/O, 150µA supply current, no internal hysteresis, SOT-23-5 package | Requires four separate devices and PCB area vs. single MAX9095ASD+ SO-14; lacks integrated hysteresis | Choose only if board space permits discrete layout and design can accommodate external hysteresis network |
Compared with LM339DR and TLV331IDR, MAX9095ASD+ delivers faster response (100ns vs. µs-scale), built-in noise immunity (2mV hysteresis), and quad integration in one SO-14 package-reducing BOM count, layout complexity, and validation effort for portable and automotive systems.

FAQ
What is the maximum operating temperature for MAX9095ASD+?
The MAX9095ASD+ is specified for continuous operation from −40°C to +125°C, with junction temperature limited to +150°C. This rating is fully tested and guaranteed per the datasheet's automotive temperature range specification, making MAX9095ASD+ suitable for under-hood automotive modules and industrial edge nodes without thermal derating.
Does MAX9095ASD+ include internal hysteresis, and how does it affect design?
Yes, MAX9095ASD+ includes 2mV of internal hysteresis-exclusive to the MAX9093/MAX9095 variants. This eliminates the need for external positive-feedback resistors in noisy environments, simplifying PCB layout and improving reliability in applications like motor current sensing or battery voltage monitoring where slow-moving or noisy inputs could cause output oscillation.
Can MAX9095ASD+ operate from a 1.8V supply, and what performance changes occur?
Yes, MAX9095ASD+ is fully specified down to +1.8V supply. At 1.8V, propagation delay increases to 120ns (tPLH), supply current drops to 210µA typical, and output saturation voltage rises to 56mV (ISINK ≤ 1mA). Input common-mode range shrinks to −0.1V to +1.0V, but rail-to-rail functionality is retained within that span.
What package type is used for MAX9095ASD+, and is it RoHS-compliant?
MAX9095ASD+ uses a 14-pin SO (Small Outline) package with 1.27mm lead pitch, JEDEC MS-012AC outline, and RoHS-compliant lead-free finish ("+" suffix denotes compliance). Thermal resistance is θJA = 84°C/W and θJC = 34°C/W, supporting power dissipation up to 952mW at +70°C ambient.
How does the open-drain output configuration of MAX9095ASD+ benefit system design?
The open-drain outputs of MAX9095ASD+ allow wired-OR connection of multiple comparators, level translation across different logic families (e.g., 5V sensor signal to 1.8V MCU), and direct drive of LEDs or MOSFET gates without external pullup conflicts. Each output sinks ≥10mA at VOUT ≤ 1.5V, enabling robust interfacing without buffer stages.
