AEC-Q100 qualified single op amp for automotive signal chains
Packaged in a SOT-23-5, it fits space-constrained PCB layouts common in engine control units, body controllers, and sensor interface modules.
The 1.8 V minimum supply lets this part run directly from a 1.8 V logic rail or a 3.3 V automotive LDO without a separate op-amp supply. The 5.5 V maximum covers 5 V nominal rails with margin for load-dump transients that stay under the absolute maximum. The 116 µA supply current per amplifier keeps the total current budget low in always-on sensor modules.
Input offset and bias current — signal-path accuracy
For a 10 kΩ source impedance, the offset from bias current adds 140 µV, which combined with the 1 mV offset stays under 1.2 mV worst-case. This is adequate for 8-bit to 10-bit accuracy in current-sense or temperature-sense circuits. If sub-millivolt precision is needed, a zero-drift amplifier would be a better fit.
Package and footprint — SOT-23-5 layout notes
The 5-pin footprint matches the industry-standard SOT-23-5 land pattern. For continuous output currents near 100 mA, keep the ambient below 85°C or add airflow.
