AEC-Q100 dual op-amp for 125°C automotive environments
The 4 MHz gain-bandwidth product and 10V/µs slew rate are sized for signal conditioning loops in the 100 kHz to 500 kHz range — think PWM current-sense amplifiers, thermocouple linearization, or CAN transceiver reference buffers.
The 3 V minimum supply lets this part run directly from a 3.3 V automotive MCU rail, while the 36 V maximum covers 24 V truck systems and 12 V passenger-car load-dump transients without external clamping. The 4 mA quiescent supply current per amplifier is moderate — not a micropower part, but acceptable for always-on modules where the ECU is already drawing tens of milliamps.
Package and footprint — 8-SSOP-B (LSSOP 4.4 mm wide)
Housed in an 8-lead LSSOP with 4.40 mm body width (ROHM package code 8-SSOP-B), the BA3472WFV-CE2 occupies roughly half the board area of a standard SOIC-8. The 0.65 mm pitch demands careful solder-paste stencil design for automotive-grade reflow profiles.
