For engineers reviewing the JM38510/11202BGA datasheet, JM38510/11202BGA pinout, JM38510/11202BGA application, or JM38510/11202BGA equivalent, key selection criteria include its −55°C to +125°C operating temperature range, 76 dB common-mode rejection, 5.0 µs typical response time, and MIL-STD-883 Class B conformance for high-reliability embedded control and signal conditioning.

Technical Context

The JM38510/11202BGA implements two independent PNP-input comparators with rail-to-rail input common-mode range including ground, enabling single-supply threshold sensing without level-shifting. Its output stage uses uncommitted NPN collectors capable of wired-OR configurations and sinking up to 20 mA.

Designed for military applications, it undergoes full MIL-STD-883 Group A testing across −55°C, 25°C, and +125°C, with guaranteed DC parameters including input bias current ≤100 nA (typ), input offset current ≤±3 nA (typ), and output saturation voltage ≤250 mV at 4 mA load.

FAQ

What is the maximum junction temperature rating for JM38510/11202BGA?

The maximum junction temperature (T_Jmax) for JM38510/11202BGA is 175°C, as specified in the Absolute Maximum Ratings table. This rating supports sustained operation in high-temperature avionics bays and engine-mounted electronics when combined with proper thermal design using its TO-99 package θ_JA of 174°C/W (still air). The device maintains full parameter compliance across its −55°C to +125°C ambient operating range, and JM38510/11202BGA must be derated per standard thermal equations above 125°C ambient.

Does JM38510/11202BGA support dual-supply operation?

Yes, JM38510/11202BGA supports dual-supply operation from ±2.5 VDC to ±18 VDC, as confirmed in the Features section and Absolute Maximum Ratings. This allows symmetric biasing for AC-coupled signal comparisons and eliminates DC offset errors in precision instrumentation. The input common-mode voltage range includes ground under both single- and dual-supply conditions, and JM38510/11202BGA maintains its 5 mV max offset voltage specification across all valid supply configurations.

Can JM38510/11202BGA outputs be wired together?

Yes, JM38510/11202BGA outputs are open-collector NPN transistors and can be directly wired together (wired-OR) with a shared pull-up resistor. This configuration is explicitly supported in the Applications Hints section and enables fault-bus architectures where multiple comparators drive a single interrupt line. Each output can sink up to 20 mA continuously, and JM38510/11202BGA maintains output saturation voltage ≤250 mV at 4 mA even under this configuration.

What is the input leakage current specification for JM38510/11202BGA?

The input leakage current for JM38510/11202BGA is ±500 nA maximum at +V_CC = 36 VDC and input voltages of 0 V or 34 V, as specified in the Electrical Characteristics table under "+IIL" and "−IIL". This low leakage preserves accuracy in high-impedance sensor interfaces such as piezoelectric accelerometers or photodiode amplifiers. The value applies across the full −55°C to +125°C operating range, and JM38510/11202BGA exhibits no significant drift with temperature or supply variation.

Is JM38510/11202BGA RoHS compliant?

No, JM38510/11202BGA is not RoHS compliant, as indicated in the Package Option Addendum where the RoHS column states "No" for all variants including JM38510/11202BGA. It contains leaded solder and is manufactured to MIL-STD-883 requirements that permit Pb-based finishes for hermetic reliability. For RoHS-compliant alternatives, consult TI's LM2903VQDRG4Q1 or LM393QPWR, though neither matches the military temperature range or screening of JM38510/11202BGA.
