Quad op-amp for multi-channel signal conditioning
The BA14741F-E2: The BA14741F-: The ROHM BA14741F- is a general-purpose quad operational amplifier in a 14-SOP surface-mount package, offering four independent amplifiers in one 14-SOIC footprint. It delivers a 2 MHz gain-bandwidth product and a 1V/µs slew rate, suited for audio pre-amplification, active filters, sensor signal buffering, and control-loop conditioning in industrial and consumer equipment. The supply range spans 4 V to 36 V, covering single-supply 5 V logic rails up to 24 V industrial buses.
The 4 V minimum supply means this op-amp runs directly from a 5 V rail without a boost converter, and the 36 V maximum lets it operate on 24 V industrial supplies with headroom for transients. The 3 mA supply current per device (all four amplifiers active) is moderate; if your design runs on battery power, consider a lower-power quad like the BA10358FJ-GE2 (500 kHz GBWP, 0.5 mA supply) for always-on sense circuits.
Temperature range and production status
ROHS3 compliant, no lead or restricted substances.
Sourcing and quoting
The 14-SOP footprint is shared with many standard quad op-amps, so a second-source qualification (e.g., against the BA4558RF- dual, or a pin-compatible quad from another vendor) is straightforward for dual-sourcing programs.
