Dual op-amp in a 1.4 mm² footprint
The LM2904ITP/NOPB: It belongs to the LM2904 family, a workhorse industrial-grade dual op-amp line known for single-supply operation from 3 V to 32 V and a 1 MHz gain-bandwidth product.
What the parametrics mean on the bench
The 45 nA typical input bias current is low enough for most resistive sensor interfaces (thermocouples, strain gauges with 10 kΩ bridges) but not for high-impedance sources like photodiode front-ends where a CMOS-input part would be a better fit. Input offset voltage is 2 mV typical — adequate for non-critical DC accuracy; if you need sub-mV precision, a chopper-stabilized or zero-drift amplifier would be the next step up. The 3 V to 32 V supply span means this part runs on a single 5 V or 24 V industrial rail without a negative supply — the output swings close to the rails, though not fully rail-to-rail. For a 5 V single-supply system, the input common-mode range includes ground, which simplifies single-supply designs.
Active lifecycle and packaging
The 8-DSBGA package (0.5 mm pitch, 0.4 mm ball diameter) requires a controlled reflow profile and X-ray inspection for voiding — standard for wafer-level chip-scale packages. The supplier device package is 8-DSBGA, identical to the package/case field.
