The LM2904WN is a dual-channel general-purpose operational amplifier from STMicroelectronics in an 8-DIP through-hole package.
The amplifier operates from a single or split supply spanning 3 V to 30 V. Input bias current is 20 nA typical and input offset voltage is 2 mV typical — figures that keep DC errors manageable in precision circuits without requiring a chopper-stabilised architecture.
Buyers need a direct drop-in or functional alternative since the part is obsolete.
Obsolete status often still has stock at surplus distributors; buyer needs to know if they can source it now.
Designers must verify electrical specs, pinout, and application notes for their circuit.
Even for obsolete parts, remaining stock may have varying lead times; buyer needs to plan procurement.
Technicians replacing a failed unit need to confirm pin compatibility with the existing board.
Common cross-reference question; buyer wants to know if a similar part from same family works.
