Quad CMOS op-amp for general-purpose signal chains
The BU7244FV-E2: The 14-LSSOP package (4.40 mm width) fits space-constrained PCBs.
The 900 kHz gain bandwidth product sets the usable frequency for closed-loop gain. The 0.4 V/µs slew rate limits large-signal response.
Supply range and input bias — BOM-fit checks
The 1.8 V minimum supply lets the quad op-amp run directly from a single Li-ion cell or a 1.8 V logic rail, while the 5.5 V maximum covers 5 V ±10% systems. Input bias current is 1 pA typical — negligible for high-impedance sensors like photodiodes or pH probes. Input offset voltage is 1 mV, which is typical for a general-purpose CMOS amplifier; for precision DC applications below 1 mV offset, a chopper-stabilized part would be needed.
Package and footprint — 14-LSSOP
It is a surface-mount, fine-pitch SOIC-like footprint. The tape-and-reel option is standard for automated pick-and-place.
For production BOMs with a multi-year horizon, this part presents no imminent obsolescence risk. The quad-channel configuration consolidates four op-amps into one package, reducing PCB area and component count versus four single-channel devices.
