Product details
Overview
MAX9024AUD+T from Analog Devices is a quad micropower comparator optimized for battery-powered portable systems, featuring 2.8μA supply current per comparator, 3μs propagation delay, 4mV internal hysteresis, rail-to-rail output swing, and operation from 2.5V to 5.5V single supply across -40°C to +125°C.
For engineers reviewing the MAX9024AUD+T datasheet, MAX9024AUD+T pinout, MAX9024AUD+T application, or MAX9024AUD+T equivalent, key selection considerations include ultra-low quiescent current, built-in hysteresis for noise immunity, TSSOP-14 package footprint, and guaranteed performance over automotive temperature range.
Technical Context
The MAX9024AUD+T implements four independent comparators with matched input offset voltage (±1mV typical), common-mode input range extending from VSS to VDD – 1.1V, and no phase reversal under overdriven inputs. Its output stage minimizes switching current to suppress supply glitches during transitions.
Each comparator features 4mV internal hysteresis centered on its input offset voltage, enabling stable threshold detection without external feedback. The device supports dual-supply operation (±1.25V to ±2.75V) and tolerates input voltages up to VDD + 0.3V relative to VSS.
Key Specifications

| Common-Mode Range | VSS to VDD – 1.1V - accommodates ground-referenced sensors and high-side signal monitoring |
Pinout & Package
The MAX9024AUD+T is housed in a 14-pin TSSOP package (JEDEC MO-153, 5.0mm × 4.4mm × 1.2mm), RoHS-compliant, with exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTD | Comparator D output - open-drain compatible, rail-to-rail capable |
| 2 | IND− | Comparator D inverting input - accepts signals down to VSS |
| 3 | IND+ | Comparator D noninverting input - supports common-mode up to VDD − 1.1V |
| 4 | VSS | Negative supply - must be connected to system ground or negative rail |
| 5 | VDD | Positive supply - requires 0.1μF ceramic bypass capacitor to VSS |
| 6 | INA+ | Comparator A noninverting input - electrically isolated from other inputs |
| 7 | INA− | Comparator A inverting input - matched offset and bias current with INA+ |
| 8 | OUTA | Comparator A output - identical drive capability to OUTD |
| 9 | OUTB | Comparator B output - independent sourcing/sinking path |
| 10 | INB− | Comparator B inverting input - shares same electrical specs as INA− |
| 11 | INB+ | Comparator B noninverting input - fully differential input pair |
| 12 | OUTC | Comparator C output - decoupled from other outputs for timing isolation |
| 13 | INC− | Comparator C inverting input - low input bias current (3nA typical) |
| 14 | INC+ | Comparator C noninverting input - supports rail-to-rail common-mode range |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339DR | Higher supply current (250μA/comparator), no internal hysteresis, wider supply range (2V–36V) | Requires external hysteresis resistors; suited for high-voltage industrial sensing, not ultra-low-power portable use | Select LM339DR only when operating above 5.5V or requiring higher drive strength |
| TLV3704IPW | Lower supply current (1.8μA/comparator), rail-to-rail input, but no internal hysteresis and slower propagation (6μs) | Lacks integrated noise immunity; demands careful PCB layout and external filtering for noisy environments | Choose TLV3704IPW when lowest possible current dominates and hysteresis can be added externally |
Compared with LM339DR and TLV3704IPW, the MAX9024AUD+T uniquely delivers 2.8μA current, 4mV hysteresis, and 3μs speed in a single TSSOP-14 package - making it optimal for space-constrained, battery-operated systems needing robust threshold detection without design overhead.

FAQ
What is the operating temperature range for the MAX9024AUD+T?
The MAX9024AUD+T is specified for continuous operation from -40°C to +125°C, meeting AEC-Q100 Grade 0 requirements for automotive under-hood applications. This range is guaranteed by design and validated through production testing at temperature extremes. All electrical parameters-including supply current, propagation delay, and hysteresis-are characterized across this full range. The MAX9024AUD+T maintains 2.8μA typical supply current and 3μs propagation delay even at +125°C.
Does the MAX9024AUD+T require external hysteresis components?
No, the MAX9024AUD+T includes 4mV of internal hysteresis per comparator, eliminating the need for external positive-feedback resistors in most threshold-detection applications. This hysteresis is factory-trimmed and remains stable across temperature and supply voltage. External hysteresis may still be added using two resistors if a wider band (e.g., 50mV) is required, but the MAX9024AUD+T operates reliably out-of-the-box for standard noise-immune detection tasks.
What is the maximum capacitive load the MAX9024AUD+T output can drive?
The MAX9024AUD+T output is stable with capacitive loads up to 150pF, as verified by characterization data showing no sustained oscillations. For loads exceeding 150pF, a series resistor (typically 10Ω–50Ω) should be placed close to the output pin to isolate the comparator from excessive capacitance. This limit applies independently to each of the four outputs, allowing mixed loading configurations without cross-talk degradation in the MAX9024AUD+T.
Can the MAX9024AUD+T operate from dual supplies?
Yes, the MAX9024AUD+T supports dual-supply operation from ±1.25V to ±2.75V, in addition to its primary 2.5V–5.5V single-supply mode. When used with dual rails, the VSS pin connects to the negative supply and VDD to the positive supply. Input common-mode range extends from VSS to VDD – 1.1V in either configuration. The MAX9024AUD+T retains all specifications-including 4mV hysteresis and rail-to-rail output-under dual-supply conditions.
Is the MAX9024AUD+T pin-compatible with other quad comparators in the MAX902x family?
Yes, the MAX9024AUD+T shares identical pinout and functionality with the MAX9024ASD+T (SO-14 package), enabling direct substitution between TSSOP and SO packages without PCB changes. Both variants use the same 14-pin mapping for VDD, VSS, and all four comparator inputs/outputs. However, the MAX9024AUD+T is not pin-compatible with dual or single comparators in the same family (e.g., MAX9022 or MAX9021), as those use different pin counts and assignments.
