AEC-Q100 dual op-amp in a hermetic CDIP-8
It delivers a 45 V/µs slew rate and 5.9 MHz gain-bandwidth product, with rail-to-rail output swing. This combination of hermetic sealing, wide temperature range, and automotive-grade qualification makes it suited for under-hood sensor conditioning, actuator drive, and signal-chain stages in ECUs where plastic packages are not acceptable.
The TLE2142AMJG operates from a single or split supply spanning 4 V to 44 V. On a nominal 12 V or 24 V automotive bus, this leaves margin for cold-crank dips and load-dump transients. The 6.9 mA quiescent current per dual channel is reasonable for always-on modules that must stay within a sleep budget.
DC precision and input characteristics
These are adequate for general-purpose signal conditioning — pressure sensor or thermocouple amplification — but not for precision microvolt-level stages. The 700 nA bias current is bipolar-input typical; for high-impedance sources like piezo sensors, a CMOS-input op-amp would be a better fit. The 45 V/µs slew rate and 5.9 MHz GBW support fast PWM signal filtering and comparator-like applications without excessive phase lag.
It is not subject to a last-time-buy notice. No official second-source or direct pin-compatible replacement is listed in the manufacturer's cross-reference for this specific AEC-Q100 CDIP variant.
