It features a 1MHz gain-bandwidth product while consuming only 45uA supply current, giving it an excellent GBW-to-Iq ratio of 22kHz\/uA. The rail-to-rail input stage uses a complementary N-channel\/P-channel input pair that covers the full supply range from V- to V+. The rail-to-rail output stage swings within 10mV of the rails with a 100kOhm load. The 1.8V minimum supply voltage allows operation from a single Li-Ion cell or 1.8V logic rails. The AEC-Q100 qualification ensures reliability in automotive temperature cycling and stress conditions (-40C to +125C Grade 1). The Q1 suffix specifically marks this as an automotive-grade device with controlled manufacturing flow. Applications include battery monitoring, sensor signal conditioning, and low-power filter circuits in automotive ECUs.","pin_description":"
