What this dual op-amp brings to an automotive BOM
The Texas Instruments LM2904BQDGKRQ1 is an automotive-qualified, general-purpose dual operational amplifier in an 8-VSSOP package. It delivers a gain bandwidth product of 1.2 MHz and a slew rate of 0.5 V/µs, with a supply span from 3 V to 36 V.
Supply rail flexibility and quiescent draw
The 3 V minimum supply and 36 V maximum cover battery lines with headroom for load-dump transients. Each of the two channels draws 300 µA supply current.
Input offset and bias — what to expect in production
Input offset voltage is rated at 300 µV, and input bias current at 10 nA. The push-pull output stage can source or sink 30 mA per channel.
Package and ordering variant
The LM2904BQDGKRQ1 is supplied in an 8-VSSOP package (3.00 mm width), surface-mount only. The suffix Q1 marks the automotive-grade variant with AEC-Q100 qualification.
This part is listed as Active on the manufacturer's lifecycle record. It is not approaching end-of-life, and no last-time-buy notice has been issued. For production builds, the LM2904BQDGKRQ1 can be specified into the BOM with confidence that the supply channel will remain open.
