AEC-Q100 qualification — the sourcing gate for automotive lines
The AEC-Q100 qualification is the primary reason this part appears on automotive BOMs. If your project targets a passenger-vehicle or heavy-equipment ECU, this qualification is the baseline.
The 1.2 MHz gain bandwidth product sets the usable closed-loop gain range: at a gain of 10, the -3 dB bandwidth is about 120 kHz, enough for audio-frequency filtering, motor-current sensing loops, and slow ADC driver stages. For designs that only need to condition DC or low-frequency signals (temperature, pressure, position sensors), these ratings are adequate and the low 300 µA per channel supply keeps the power budget tight.
Package and mounting — 8-SOIC on the board
The LM2904BTQDRQ1 comes in an 8-SOIC package with a body width of 3.90 mm (0.154"). It is a surface-mount part intended for standard reflow assembly. This is a common, well-characterized package that places cleanly on a standard SOIC-8 land pattern.
