STMicroelectronics has introduced AEC-Q100 Grade-0 op amps and comparators in the space-saving MiniSO8 package, giving automotive designers twice the freedom to miniaturise ECUs deployed in extreme temperature environments and safety-critical systems.

The LM2904WHYST dual op amp and LM2903WHYST dual comparator in 4.9 x 3 mm MiniSO8 are qualified for operation from -40 to 150°C, with the added advantage of 50% smaller footprint than other Grade-0 parts in standard SO8.

The wide ambient operating temperature range of the ICs ensures robust and resilient performance in systems that are exposed to harsh conditions. These include under-the-hood electronics such as engine controllers, in-gearbox modules, LED-lighting controllers and safety-critical systems such as ABS controllers that must provide absolute dependability.

The parts are developed with the benefit of ST’s extensive experience working with major automotive Tier-1 suppliers and can be individually tested up to 150°C as part of production part approval process (PPAP) tests. As industry-standard LM2903 and LM2904 devices, they deliver benchmark performance compared to familiar metrics including input bias current, input offset voltage, current consumption and supply-voltage range.
