Texas Instruments has marked the LM2904VQPWR as Obsolete. The part remains ROHS3 Compliant, so it still ships into RoHS-regulated assemblies without exemption paperwork.
Dual op-amp in 8-TSSOP — DC precision and bandwidth
The LM2904VQPWR is a dual general-purpose operational amplifier in an 8-TSSOP surface-mount package. Supply current is 500 µA for both channels, keeping the thermal budget low in dense boards.
Input offset and bias — what to expect at the bench
Input offset voltage is 3 mV and input bias current is 20 nA — typical for a general-purpose bipolar-input op-amp. For a 10 kΩ source impedance, the offset error from bias current is about 200 µV, negligible compared to the 3 mV offset.
