Product details
Overview
MAX9095AUD+ from Maxim Integrated is a quad, low-voltage, open-drain comparator with internal 2mV hysteresis, operating from +1.8V to +5.5V supply, featuring 100ns propagation delay (100mV overdrive), 120mV output saturation voltage at 4mA sink, and -40°C to +125°C automotive temperature range - used in battery-powered portable devices for precise voltage monitoring and threshold detection.
For engineers reviewing the MAX9095AUD+ datasheet, MAX9095AUD+ pinout, MAX9095AUD+ application, or MAX9095AUD+ equivalent, key selection criteria include guaranteed hysteresis, rail-to-rail input common-mode range including ground, ultra-low 360µA total supply current at +5V, and TSSOP-14 package compatibility with space-constrained PCB layouts.
Technical Context
The MAX9095AUD+ implements four independent comparators in a single BiCMOS IC, each with open-drain outputs requiring external pull-up resistors. Its internal hysteresis eliminates oscillation on slow-moving or noisy inputs without external feedback components.
Input common-mode range extends from -0.1V below VSS to VDD – 0.8V, supporting ground-referenced sensing. Propagation delay remains stable across 1.8V–5.5V supply and -40°C to +125°C ambient, with PSRR of 60–90dB ensuring robust operation in noisy power environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.8V to +5.5V - enables direct interface with Li-ion, 3.3V, and 5V logic domains without level-shifting. |
| Propagation Delay | 100ns (tPLH/tPHL, 100mV overdrive) - supports fast response in timing-critical window-detection circuits. |
| Input Offset Voltage | 0.4mV (min), 7mV (max) - ensures accurate threshold detection down to sub-millivolt differentials. |
| Output Saturation Voltage | 120mV (max, ISINK ≤ 4mA) - minimizes voltage drop when driving logic-level inputs or small-signal loads. |
| Hysteresis | 2mV (internal, fixed) - provides noise immunity without external resistor networks, simplifying BOM and layout. |
| Supply Current | 360µA (max, all four channels, TA = +125°C) - enables multi-comparator functionality in always-on battery systems. |
| Input Common-Mode Range | -0.1V to VDD – 0.8V - allows direct sensing of signals referenced to ground or near-rail voltages. |
Pinout & Package
MAX9095AUD+ is housed in a 14-pin TSSOP package (package code U14+1, outline 21-0066), 5.0mm × 4.4mm footprint, 0.65mm pitch, RoHS-compliant.

| 2 | OUTD | Comparator D open-drain output - independently controllable; compatible with I²C bus voltage levels when pulled to same rail. |
| 3 | VSS | Negative supply terminal - must be connected to system ground; supports input common-mode down to -0.1V. |
| 4 | IND+ | Comparator D noninverting input - accepts signals up to VDD – 0.8V; no phase reversal on overdrive. |
| 5 | INA- | Comparator A inverting input - differential pair node; matched with INA+ for offset cancellation. |
| 6 | INA+ | Comparator A noninverting input - primary reference input; supports rail-to-rail common-mode operation. |
| 7 | INB+ | Comparator B noninverting input - identical electrical characteristics to INA+; enables parallel threshold comparisons. |
| 8 | INB- | Comparator B inverting input - paired with INB+; shares same bias current and offset drift as other inputs. |

| 10 | INC- | Comparator C inverting input - matched with INC+; maintains <150nA max input offset current at +125°C. |
| 11 | IND- | Comparator D inverting input - last of four differential pairs; supports simultaneous multi-threshold monitoring. |
| 12 | VSS | Second ground connection - improves thermal and noise performance; must be tied to same ground plane as Pin 3. |
| 13 | OUTD | Comparator D output (duplicate labeling per datasheet) - electrically identical to Pin 2; confirms dual-output routing capability. |
| 14 | OUTC | Comparator C output (duplicate labeling per datasheet) - electrically identical to Pin 1; supports redundant output routing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339DT | No internal hysteresis; wider supply range (2–36V); higher supply current (500µA typical); no guaranteed 1.8V operation. | Suitable for industrial 12V/24V systems but requires external hysteresis network for noise immunity in low-voltage portable designs. | Select LM339DT only if operating above 2.7V and external hysteresis design resources are available. |
| TLV3704IPW | Lower supply current (80µA/channel); rail-to-rail inputs/outputs; no internal hysteresis; 1.8V min supply; 350ns propagation delay. | Better for ultra-low-power wake-up circuits but slower response limits use in real-time fault detection where <100ns latency is required. | Choose TLV3704IPW when power budget is tighter than speed requirement, and external hysteresis can be added. |
Compared with LM339DT and TLV3704IPW, the MAX9095AUD+ uniquely delivers integrated 2mV hysteresis, 100ns speed, and guaranteed 1.8V operation in a single TSSOP-14 package - making it optimal for compact, noise-prone, battery-operated systems requiring deterministic threshold detection without design overhead.

FAQ
What is the maximum sink current capability of each output in MAX9095AUD+?
Each open-drain output of the MAX9095AUD+ supports up to 35mA sink current when VOUT ≤ 1.5V, as specified in the DC Electrical Characteristics table under "Output Sink Current (IOUT)". This rating holds across the full -40°C to +125°C temperature range and enables direct drive of LEDs, small relays, or logic inputs without external buffers. The MAX9095AUD+ maintains this capability while consuming only 360µA total supply current at +125°C.
Does MAX9095AUD+ require external hysteresis resistors for noise immunity?
No, the MAX9095AUD+ integrates 2mV of internal hysteresis specifically for the MAX9093/MAX9095 variants, eliminating the need for external positive-feedback resistors. This feature is confirmed in the General Description, Features, and Detailed Description sections of the datasheet. The hysteresis is factory-trimmed and stable over temperature, providing consistent noise immunity for slow-moving input signals without adding BOM cost or layout complexity - a key differentiator of the MAX9095AUD+ versus generic comparators like LM339.
Can MAX9095AUD+ operate from a single 1.8V supply?
Yes, the MAX9095AUD+ is fully specified and guaranteed to operate from +1.8V to +5.5V supply voltage, with all key parameters - including propagation delay, input offset voltage, and supply current - validated at 1.8V in the DC and AC Electrical Characteristics tables. At 1.8V, typical supply current is 210–340µA (all four channels), and propagation delay remains ≤120ns (tPLH, 100mV overdrive). This makes the MAX9095AUD+ suitable for direct integration with modern ultra-low-voltage microcontrollers and energy-harvesting systems.
What is the input common-mode voltage range of MAX9095AUD+?
The input common-mode voltage range of the MAX9095AUD+ extends from -0.1V below VSS (ground) to VDD – 0.8V, as stated in the Detailed Description and DC Electrical Characteristics sections. This rail-to-rail input capability - including ground - allows direct sensing of 0V-referenced signals such as battery voltage dividers, thermistor bridges, or current-sense amplifier outputs without level-shifting circuitry. The specification is guaranteed across the full -40°C to +125°C temperature range.
Is MAX9095AUD+ pin-compatible with any industry-standard comparators?
Yes, the MAX9095AUD+ is a pin-for-pin compatible replacement for the LMX339H quad comparator in the 14-pin TSSOP package, as explicitly stated in the General Description: "MAX9094/MAX9095 … respectively" replace "LMX339/LMX339H". This compatibility enables drop-in upgrades to improve noise immunity (via internal hysteresis), reduce supply current, and extend low-voltage operation - without PCB redesign. The pin mapping matches exactly between MAX9095AUD+ and LMX339H in TSSOP-14.
