Overview
M38510/11202BPA from Texas Instruments is a MIL-PRF-38535 qualified dual differential comparator designed for high-reliability analog signal conditioning in harsh environments. It operates from single or dual supplies (2 V to 36 V), delivers 0.4 mA typical supply current per comparator, features 2 mV typical input offset voltage and 25 nA typical input bias current, and supports operation across –55°C to +125°C - used in motor control feedback loops, chemical sensor threshold detection, and weigh scale reference comparators.
For engineers reviewing the M38510/11202BPA datasheet, M38510/11202BPA pinout, M38510/11202BPA application, or M38510/11202BPA equivalent, key selection criteria include its open-collector output compatibility with TTL/MOS/CMOS logic, ±36 V differential input voltage range, ground-sensing common-mode input capability, and military-grade temperature and reliability qualification under MIL-PRF-38535.
Technical Context
The M38510/11202BPA implements two independent PNP Darlington-pair input stages enabling low input bias current (25 nA typ) and wide common-mode range (0 V to VCC–1.5 V at 25°C). Its open-drain NPN output stage allows wired-AND configuration and flexible logic-level translation via external pull-up.
It is characterized for full parametric testing per MIL-PRF-38535 requirements across –55°C to +125°C, with absolute maximum ratings including 36 V supply, ±36 V differential input, and unlimited output short-circuit duration to ground - confirming suitability for safety-critical industrial and aerospace monitoring circuits.
Key Specifications

Pinout & Package
Ceramic Dual In-Line Package (CDIP), 8-pin, body size 10.00 mm × 7.00 mm, hermetically sealed per MIL-STD-1835 GDIP1-T8, with SNPB lead finish and no internal connections on pins 3, 4, 5, and 6 (as confirmed in TI SLIS183 pin function table).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Open-collector output of comparator 1 - sinks current when IN– > IN+; requires external pull-up for logic-high assertion. |
| 2 | 1IN– | Inverting input of comparator 1 - accepts signals up to VCC–1.5 V; input bias current flows out of pin (sinks). |
| 3 | 1IN+ | Non-inverting input of comparator 1 - same voltage range and bias behavior as 1IN–; used for reference or signal input. |
| 4 | GND | Analog ground reference - serves as common return for both comparators and must be low-impedance for noise immunity. |
| 5 | 2IN+ | Non-inverting input of comparator 2 - electrically identical to 1IN+; enables independent dual-threshold detection. |
| 6 | 2IN– | Inverting input of comparator 2 - matches 1IN– characteristics; supports differential or single-ended sensing per channel. |
| 7 | 2OUT | Open-collector output of comparator 2 - independently controllable; supports parallel or cascaded decision logic. |
| 8 | VCC | Positive supply pin - powers both comparators; accepts 2 V to 36 V; no reverse polarity protection. |
Key Features
| Feature | Design Value |
|---|---|
| Single- or dual-supply operation | Eliminates need for split supplies in battery-powered or automotive systems; supports 2 V minimum for ultra-low-power wake-up detection. |
| Ground-sensing input stage | Enables direct interface with 0 V–referenced sensors (e.g., load cells, RTDs) without level-shifting circuitry. |
| Wired-AND output capability | Allows multiple comparators to share one pull-up resistor and output node - reduces component count in alarm or OR-gate logic. |
| MIL-PRF-38535 compliance | Guarantees full parametric testing, lot traceability, and burn-in screening - required for defense, space, and critical infrastructure programs. |
| ±36 V differential input rating | Permits direct connection across motor windings, transformer secondaries, or isolated power rails without external attenuators. |
Applications
| Motor Control: AC Induction | Chemical or Gas Sensor |
|---|---|
Use Scenario: Monitoring back-EMF zero-crossing in three-phase inverter gate drivers to synchronize commutation timing. IC Role / Device Role / Timing Role: Dual comparator detects polarity reversal of phase voltages relative to neutral; outputs drive logic sequencer for IGBT firing. Use Value: Enables sensorless FOC (Field-Oriented Control) with <1.3 µs response time and immunity to supply ripple due to wide common-mode range. |
Use Scenario: Converting electrochemical sensor output into digital alarm thresholds for toxic gas concentration (e.g., CO, H2S). IC Role / Device Role / Timing Role: Compares conditioned sensor voltage against two independent reference levels to trigger low/mid/high alert states. Use Value: Delivers stable decision points over –55°C to +125°C with <2 mV offset drift, eliminating calibration drift in unheated enclosures. |
| Weigh Scale | Desktop PC |
Use Scenario: Detecting overload and tare conditions in strain-gauge-based platform scales using bridge excitation and instrumentation amplifier output. IC Role / Device Role / Timing Role: Comparator 1 triggers "overload" flag when output exceeds upper limit; comparator 2 asserts "tare complete" when signal settles within hysteresis band. Use Value: Achieves <25 nA input bias current to prevent gain error in high-Z bridge arms; open-collector outputs interface directly with microcontroller GPIOs. |
Use Scenario: Monitoring +12 V, +5 V, and +3.3 V rail integrity in ATX power supplies for system reset generation and fan speed control. IC Role / Device Role / Timing Role: Each comparator monitors one rail against precision reference; outputs feed OR gate to assert POWER_GOOD signal. Use Value: Supports wide supply range (2–36 V) to monitor all standard PC rails simultaneously; tested to 30 V ensures margin against transient overshoot. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM2903JG | Commercial-grade (–40°C to +125°C), non-MIL tested; identical pinout and electrical specs except for reduced ESD rating (±2 kV HBM vs ±1 kV). | Lacks MIL-PRF-38535 qualification, burn-in, and lot traceability - unsuitable for defense/aerospace but lower cost for industrial controls. | Select LM2903JG only if MIL-specification is not contractually required and lifecycle assurance is not mandated. |
| LM393DR | SOIC-8 package, RoHS-compliant, rated for 0°C to +70°C; same core architecture but untested beyond commercial temp range and lacks military screening. | Not qualified for extended temperature or high-reliability use; intended for consumer/desktop applications only. | Choose LM393DR for cost-sensitive, non-critical designs where CDIP packaging and extended temperature are unnecessary. |
Compared with LM2903JG and LM393DR, the M38510/11202BPA provides guaranteed parametric performance across –55°C to +125°C, full MIL-PRF-38535 conformance, and hermetic CDIP packaging - making it the sole option for programs requiring DoD-qualified components with documented reliability data and traceable manufacturing.
