Automotive-grade dual op-amp for sensor conditioning and signal chains
It operates from 3 V to 26 V single or dual supply, delivers 700 kHz gain bandwidth, and draws 500 µA per channel typical supply current.
Key ratings that drive the BOM fit
700 kHz gain-bandwidth product sets the usable closed-loop bandwidth — adequate for low-speed sensor loops (e.g., temperature, pressure) and audio-range filtering, but not for high-speed ADC drivers or switching regulators above a few hundred kilohertz. Slew rate of 0.3 V/µs limits large-signal response; expect 10% to 90% rise time around 2.7 µs for a 1 V step. Pair with a faster amplifier if the signal path requires clean square-wave reproduction above a few kilohertz. Input offset voltage rated at 3 mV typical, input bias current 20 nA typical — both adequate for non-critical DC accuracy. For precision sub-millivolt sensing, a zero-drift amplifier would be needed. Output current capability of 30 mA per channel allows direct drive of small relays, LEDs, or the input of a downstream ADC. The 3 V minimum supply span makes it usable on 3.3 V regulated rails.
Package and footprint notes for the rework bench
Housed in an 8-SOIC package (3.90 mm width, 0.154" body), surface-mount only. Standard SOIC-8 footprint with 1.27 mm pitch. Hot-air rework profile follows typical lead-free SOP.
TI lists LM2904QDRQ1 as Active. ROHS3 compliant. No known PCN affecting form, fit, or function at this time.
