Automotive Grade-0 analog ICs to occupy 50% footprint

October 04, 2016 // By Graham Prophet
STMicroelectronics' AEC-Q100 Grade-0 op amps and comparators come in the space-saving MiniSO8 package, giving automotive designers space savings in ECUs deployed in extreme temperature environments and safety-critical systems.

The LM2904WHYST dual op amp and LM2903WHYST dual comparator in 4.9 x 3.0 mm MiniSO8 are qualified for operation from -40°C to 150°C, with the added advantage of 50% smaller footprint than other Grade-0 parts in standard SO8.

The extremely wide ambient operating temperature range of these ICs ensures robust and resilient performance in systems that are exposed to the harshest 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.

ST says that it works with major automotive Tier-1 suppliers to define such parts, which can be individually tested up to 150°C as part of Production Part Approval Process (PPAP) tests. As high-quality 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. The are priced from $0.76 (1000).
