AEC-Q100 qualification and the under-hood temperature profile
The TSV912IYST: This covers the full under-hood ambient profile — an ECU sitting near the engine block on a 105°C summer day still has 20°C of margin before the die hits the abs-max junction limit.
Signal-chain parametrics that decide the fit
8 MHz gain-bandwidth product with a 4.5 V/µs slew rate — this sets the small-signal bandwidth ceiling for sensor conditioning. A gain-of-10 stage has a closed-loop bandwidth of roughly 800 kHz, enough for knock-sensor or wheel-speed signal paths without aliasing into the ADC sampling window. Rail-to-rail output stage delivers 35 mA per channel — the output can swing within 50 mV of either rail into a 1 kΩ load, so it drives the ADC input directly without a separate buffer stage. Input bias current is 1 pA typical at 25°C, doubling every 10°C; at 125°C it sits around 64 pA, still negligible for a 10 kΩ sensor but significant for a 10 MΩ piezoelectric front-end.
Package and board-fit for ECU layouts
The 0.118-inch width fits tight channel spacing on a 4-layer automotive PCB. Surface-mount only; no through-hole variant exists.
