That extra margin at the cold end matters for cold-crank or arctic-start scenarios in engine-control or transmission modules.
2 MHz GBW, 0.65 V/µs slew rate — where it fits
With a 2 MHz gain-bandwidth product and 0.65 V/µs slew rate, this op-amp is suited for low-to-moderate-speed signal conditioning: sensor buffering, filter stages, and control loops in automotive ECUs, industrial process controllers, and avionics. The 200 µA supply current keeps the power budget lean for always-on modules. Input offset voltage is 120 µV typical, and input bias current is 25 nA — adequate for precision analog work where the source impedance is moderate.
Supply range and package — design-in notes
The TLE2021MLB operates from a single or dual supply spanning 4 V to 40 V total. That wide compliance covers 5 V and 12 V automotive rails, 24 V industrial buses, and ±15 V lab supplies. The TO-99-8 metal can has eight leads on a 0.230-inch diameter circular footprint; the metal case is internally connected to the negative supply pin, so the heatsinking path is through the can itself. For high-reliability or sealed-environment builds, the hermetic package eliminates moisture ingress concerns that plague plastic packages in condensing or high-humidity conditions.
Lifecycle and sourcing
It is listed as RoHS non-compliant, which is expected for a hermetic metal-can package that predates the RoHS directive; this does not affect availability but may restrict use in jurisdictions with strict RoHS enforcement unless an exemption applies.
