Product details
Overview
JM38510/11202BPA from Texas Instruments is a military-grade dual differential comparator IC designed for high-reliability analog signal comparison 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 from −55°C to +125°C - enabling use in precision motor control feedback, chemical sensor threshold detection, and weigh-scale reference comparison.
For engineers reviewing the JM38510/11202BPA datasheet, JM38510/11202BPA pinout, JM38510/11202BPA application, or JM38510/11202BPA equivalent, key selection criteria include its open-collector output architecture, ground-sensing input capability, wide common-mode range (0 V to VCC − 2 V), MIL-PRF-38535 compliance, and compatibility with TTL/MOS/CMOS logic interfaces.
Technical Context
The JM38510/11202BPA implements two independent comparators with PNP Darlington-pair inputs, enabling low input bias current (25 nA typ) and high DC gain while maintaining rail-to-rail input common-mode operation down to ground. Its open-drain NPN output stage allows wired-AND functionality and flexible logic-level translation via external pull-up.
It is characterized across −55°C to +125°C per MIL-PRF-38535 requirements, with absolute maximum ratings including ±36 V differential input voltage and 36 V supply voltage. Input offset voltage remains stable at 2 mV (typ) over temperature, and response time is 1.3 µs (typ) with 100-mV overdrive at 25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2 V to 36 V - supports direct interface with industrial 24-V systems and low-power 3.3-V logic without level shifters. |
| Input Offset Voltage | 2 mV (typ) - enables accurate threshold detection within ±2 mV at room temperature, critical for precision sensor interfaces. |
| Input Bias Current | 25 nA (typ) - minimizes loading on high-impedance sources such as thermistors or pH electrodes. |
| Common-Mode Input Range | 0 V to VCC − 2 V - allows direct ground-referenced sensing and compatibility with single-supply sensor outputs. |
| Output Type | Open-collector NPN - permits wired-AND logic, programmable pull-up voltage, and interfacing with mixed-voltage digital systems. |
| Operating Temperature | −55°C to +125°C - qualified for aerospace, defense, and downhole industrial applications requiring extended thermal stability. |
| Response Time | 1.3 µs (typ, 100-mV overdrive) - suitable for real-time overcurrent protection and fast analog-to-digital decision circuits. |
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. Pin 1 is index-marked on cap; leads are tin-lead (SNPB) finished.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Comparator 1 output | Open-collector NPN drain - sinks current when IN− > IN+ + VIO; requires external pull-up for logic-high state. |
| 1IN− | Comparator 1 inverting input | Negative input terminal of first comparator - accepts signals within 0 V to VCC − 2 V common-mode range. |
| 1IN+ | Comparator 1 non-inverting input | Positive input terminal of first comparator - same common-mode constraints as 1IN−; used for reference or signal input. |
| GND | Ground reference | Analog ground return for both comparators and internal circuitry - must be low-impedance for noise immunity. |
| VCC | Positive supply | Main power pin - supports up to 36 V; supply current is independent of voltage (0.4 mA/comparator typ). |
| 2OUT | Comparator 2 output | Independent open-collector output - electrically isolated from 1OUT; enables dual-threshold or window-comparator configurations. |
| 2IN− | Comparator 2 inverting input | Second comparator's negative input - identical electrical specs and layout sensitivity as 1IN−. |
| 2IN+ | Comparator 2 non-inverting input | Second comparator's positive input - fully independent; allows simultaneous comparison of two signal pairs. |
Key Features
| Feature | Design Value |
|---|---|
| Single- or dual-supply operation | Eliminates need for split supplies in battery-powered or 24-V industrial systems - simplifies power architecture. |
| Input common-mode range includes ground | Enables direct interface with 0-V referenced sensors (e.g., load cells, RTDs) without level-shifting circuitry. |
| Differential input voltage range = ±36 V | Permits robust operation with large signal swings or noisy environments without input clamping diodes. |
| Low input bias current (25 nA typ) | Reduces measurement error in high-impedance transducer circuits - critical for gas/chemical sensor front-ends. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM193FKB | LCCC-20 package; same electrical specs; higher pin count, different thermal resistance (RθJC = 5.61°C/W vs 14.5°C/W for CDIP). | Suitable for space-constrained PCBs requiring hermetic sealing but not DIP footprint; better thermal performance under high ambient. | Select LM193FKB when board area is limited and thermal dissipation exceeds CDIP capability; verify socket compatibility. |

FAQ
What is the operating temperature range of the JM38510/11202BPA?
The JM38510/11202BPA is specified for continuous operation from −55°C to +125°C, fully qualified per MIL-PRF-38535 requirements. This range is validated across all electrical parameters including input offset voltage, supply current, and response time - ensuring reliable performance in avionics, engine control units, and downhole instrumentation where thermal extremes are routine. The JM38510/11202BPA maintains its 2 mV typical offset and 1.3 µs response time across this full range.
Does the JM38510/11202BPA support single-supply operation?
Yes, the JM38510/11202BPA supports true single-supply operation from 2 V to 36 V. Its input common-mode range extends to ground (0 V), and the output stage functions correctly with VCC referenced only to GND - eliminating need for negative rails. This capability is confirmed in the datasheet's Recommended Operating Conditions table and Functional Description section. The JM38510/11202BPA is routinely deployed in 5-V and 24-V single-rail industrial controls without modification.
What is the input offset voltage specification for the JM38510/11202BPA?
The JM38510/11202BPA has a typical input offset voltage of 2 mV at 25°C, with a maximum of 9 mV across the full −55°C to +125°C operating range. This parameter is measured under standard test conditions (VCC = 5 V to 30 V, VIC = VICR min, VO = 1.4 V) and is guaranteed per MIL-PRF-38535 testing protocols. The low offset enables high-accuracy threshold detection in applications like precision weigh scales and sensor fault monitoring - where the JM38510/11202BPA delivers consistent performance without trimming.
Can the outputs of the JM38510/11202BPA be wired together?
Yes, the open-collector outputs of the JM38510/11202BPA support wired-AND configuration. When multiple outputs share a common pull-up resistor, the net output is low if any comparator asserts - enabling logic gating, fault aggregation, or window-comparator implementations. This behavior is explicitly documented in the device description and functional block diagram. The JM38510/11202BPA's output transistor is rated for 20 mA sink current, supporting robust wired-AND bus designs in safety-critical systems.
Is the JM38510/11202BPA RoHS compliant?
No, the JM38510/11202BPA is not RoHS compliant. Its lead finish is tin-lead (SNPB), and the packaging material type is designated "No" under RoHS in the official TI orderable addendum. This reflects its heritage as a military-specification component built to MIL-PRF-38535 standards, where leaded finishes are retained for solder joint reliability and thermal cycling endurance. For RoHS-compliant alternatives, consult TI's LM2903 or LM393 families - though these lack the extended temperature and screening rigor of the JM38510/11202BPA.
